Phentermine for Weight Loss (Obesity/Overweight) "I was prescribed phentermine/Adipex for weight loss after I discussed with my doctor my lack of energy being a full-time single working mother. Time and motivation were really my issues contributing to my weight. She said this would give me the motivation and 'want' to exercise and is an appetite suppressant. Those two things are very true. I work a desk job and cannot exercise until evening, so that is hard. On day 1 and 2, I was on the go all day and felt fantastic, full of energy, and very happy. On day 3, I had several negative side effects of high blood pressure, heart pounding, fatigue, insomnia. On day 4, I had the dose cut in half by my doctor. Today is Friday, day 5, and I have lost 9.5 pounds since Monday. Hoping to see more loss but slower!"

Phentermine for Weight Loss (Obesity/Overweight) "I have been taking Adipex for 4 days now. I have lost 13 pounds somehow. I changed my eating to only intake 1000 calories a day. I take half a pill in the morning and half a pill at noon. I have severe dry mouth and drink about 10 bottles of water a day. I am having trouble sleeping for the last 2 days. I get the jitters really bad about 30 mins after I take the pill, it lasts for a few hours. No issues with my heart rate! I am hungry until my stomach hurts. I was an overeater, so it's pretty painful! With all that, this pill is worth it. I am excited about my progress so far and can't wait to see what I can get down to in a few months!"

Phentermine for Weight Loss (Obesity/Overweight) "This is the low dose (8 mg) Phentermine that is theoretically designed to be taken up to three times per day. Years ago, I took the full strength 37.5 mg Phentermine and felt like I was going to die and couldn’t sleep. This low dose for me is totally different. I still feel a little “wired,” but my blood pressure and heart rate are normal, and if I don’t take it too late, I can sleep okay (although I have honestly had sleep problems anyway, so I can’t evaluate that well). This dosage is way lower, so you will have to be more careful with what you eat. You will have to take it at least twice per day (maybe three if it doesn’t bother your sleep and you have a lot of weight to lose). I really am glad doctors discovered that lower dose Phentermine works pretty well because I just couldn’t tolerate the side effects of the higher dose, but this lower dose is doable. Drink lots of water and do NOT drink caffeine or take other stimulants on this."

Phentermine for Weight Loss (Obesity/Overweight) "I began taking Adipex in August 2008. I have been sticking to my doctor's weight loss plan of a 600-calorie per day diet. It has been 6 weeks, and I have lost 23 pounds. I feel so much better and plan to continue Adipex and my diet plan until I reach my goal weight. When first beginning Adipex, I had some trouble sleeping and found that I was dizzy often. Keeping some hard candy in my purse to eat when feeling dizzy seemed to help level out my blood sugar. After the first couple of weeks, sleeping and dizziness troubles went away. I feel that with the amount of weight I have already lost in a short amount of time, this drug is totally worth any and all of the side effects that I experienced."

For Weight Loss (Obesity/Overweight) "This is my second round with phentermine. I tried it a couple of years ago and lost 20 pounds and have kept it off. I decided I needed to lose 20 more, so I'm back on it as of yesterday. I'm already down 2 pounds! My appetite is virtually gone! I feel really good and have so much energy! The only downside is insomnia, but I can live with that as long as I'm getting great results!"

For Weight Loss (Obesity/Overweight) "I use only 15 mg (doc prescribed 30, but I could not sleep at all with 30 mg, also, it was so strong I did not have an appetite at all, and I would take only 300 calories per day, if that much). So 15 mg works for me. I count calories, I do not go over 1400 per day, I run/walk 30 minutes per day, drink one gallon of water, and eat everything in small portions like 5x per day. My snack is apples or almonds, but I also eat a sandwich once in a while or spaghetti or rice. The only thing I do not consume is chocolate or any other sweets. My carbs come from fruit or baked potatoes or corn... I went from 246.5 to 229 since August 1 (so in 25 days, almost 18 lbs). I will probably lose a few more until Monday, so I think a total of 20 lbs per month is great."

Phentermine for Weight Loss (Obesity/Overweight) "Adipex (phentermine) is great for weight loss. I did experience minor side effects (i.e., dry mouth, insomnia). I have taken this medicine on and off for several years. I noticed rapid weight loss the first time I took it, losing over 30 pounds in the first month. I was 202 lbs when I took it the first time, and after only 1 month, I was down to about 170 lbs. I went off of the medicine for several months, didn't exercise, and returned to my original eating habits, regaining all of the weight plus some. The second time I took it, I didn't experience the same rapid weight loss I had with the first attempt, only getting down to about 182 lbs. Going for try #3 but will do it right this time with exercise and diet change for life!"

Phentermine for Weight Loss (Obesity/Overweight) "I am 5'3, and when I started Adipex in late January, I was 202 lbs. Just now starting to slowly stop taking them by skipping days. I have had a total weight loss of 38 lbs in 3 months. The first month was the quickest results. I've eaten 1200 calories daily, drank water, and worked out extremely for 4-5 times a week. Experience headaches due to lack of water sometimes. I was dizzy when standing up too fast, had many sleepless nights from too much energy, even though my body was so tired. But I feel reborn. I feel so happy and confident. Of course, my body image isn't what I expected, but my journey has not ended yet. Adipex is a tool used to help change your lifestyle. I can't wait to say I changed my lifestyle and no longer need a pill, but I am thankful for it."

For Weight Loss (Obesity/Overweight) "Started taking phentermine on 9-26-14. I weighed 196 lbs. I had my first weigh-in today, 10-9-14, and I now weigh 187 lbs. I lost 9 lbs in 2 weeks. The side effects I'm having are dry mouth, headaches, and stomach pains, but that could be my loss of appetite throughout the day and not eating. I'm also experiencing insomnia. I was taking the pill at 10 am. I am now switching to half a pill and taking it at 8 am. I will see if it works better for me."

For Weight Loss (Obesity/Overweight) "I have been using Phentermine for the past week, and it works! I have already lost 7 lbs in 1 week with diet and exercise as well. In the beginning, I was very apprehensive about this. I have friends who have used it, and it also worked for them. I did experience a few side effects, such as dizziness, heart palpitations, and insomnia, but once my body got used to it, I felt fine. As a nurse, mother of two, and someone who juggles two jobs, Phentermine gave me the energy I needed. When I left work at 5 pm, I would pick up the kids, make dinner, do homework, and still have energy for an hour and a half, 5-6 days a week of exercise at the local 24/7 gym. So, thumbs up for Phentermine!"

Phentermine for Weight Loss (Obesity/Overweight) "I took Adipex for the past 3 months as prescribed. I weighed 190 lbs. with type 2 diabetes and high blood pressure. The first month I lost 20 lbs. The 2nd month 4 lbs. and 3rd month 4 lbs. I played volleyball 2x a week, which helped. I could have lost more, but I hate exercising if it's not volleyball. My 1st month, the insomnia was nightly. The dry mouth was all the time. Try chewing gum. I drank more water than I'm used to, but it was good for me. Constipation was a problem. Try fiber pills or Phillips or stool softener for constipation. Lots of energy. 2nd month, sleep was better. I felt great because I could feel those 20 lbs. off and my clothes were so baggy. Lots of energy. I slightly started to want to eat. 3rd month. Total loss = 28 lbs."

Phentermine for Weight Loss (Obesity/Overweight) "I have been on Adipex for almost two years. When they say it's not such a thing as a miracle pill, they haven't tried this. I lost 10 pounds from my goal of losing 150 pounds. My weight loss has slowed down a bit, but as long as the numbers go down and not up, I'm still happy. I did experience extremely dry mouth, dizziness, and loss of appetite for the first two months. BUT IT WAS WORTH EVERY BIT. Now I'm starting to have sleeping problems, which I don't like. I am very scared that if I stop taking it, I'm going to gain my weight back."

Phentermine for Weight Loss (Obesity/Overweight) "Been on Adipex-P for 28 days and have lost 20 pounds. Doctor put me on it because I am menopausal and have a hard time losing weight. First week had a hard time sleeping, but now no problems. I check my blood pressure daily and no issues there. Definitely get dry mouth with it, that has been my only issue. I usually chew gum and keep a drink handy. Glad I was given this drug, doubt I would have lost what I did without it."

Phentermine for Weight Loss (Obesity/Overweight) "I do have ADD, and this is a low-grade amphetamine, so for someone who doesn’t have ADD, these may work. I am not sure why my doctor chose to put me on these, as they do the complete opposite for me. Since I do have ADD, they stabilize me rather than stimulate. The side effects include insomnia, high BP, lower appetite, and boost energy. I am not a person who naps, I can run on 5 hours of sleep, and these made me SO TIRED after taking them. They didn’t give me high BP, they didn’t cause insomnia, they didn’t give me energy, and they did not lower my appetite. They did give me brain fog. You’re apparently supposed to lose 2 lbs per week on these pills. My doctor had me on one 8 mg tablet, then wanted to bump it up to one and a half. I did not continue the meds because even after a month, change in diet, and consistent working out and walking, they still did nothing for me. I started these at 226 and have actually been fluctuating between 237-230 since taking them. I do not recommend."

For Weight Loss (Obesity/Overweight) "I have had a lot of success with Phentermine 37.5 mg. The first time was 3 years ago when I lost 30 pounds in 2 months. I am 5'3" and weighed 180, and after 2 months on Phentermine, I was at 150. This time I am 45 years old and started out at 165, and after 1 month, I weigh 150, so I have lost 15 pounds, which is the same rate I lost the weight before. I do take the pill early in the morning around 6 am, if I do not, I do experience insomnia. I get full very fast, after only taking a few bites of something, I am done, or I become nauseous. Phentermine has also caused me to have a dry mouth, you just have to drink a lot of water, which is good for you anyway. All in all, my experience has been very good. It does really work. Just have a physical first."

For Weight Loss (Obesity/Overweight) "I was just like you, reading the reviews about this weight loss medicine. Always go with your first mind, if your first mind tells you no, just go with it. If you are a person who suffers from anxiety or depression in the past, this is not for you. I had a baby 2 months ago and wanted my baby weight off so bad, but this made my anxiety come back. I was only taking this for five days at a dose of 37.5 mg, whole pill. Also messed with my mental health, had insomnia, and brought on depression. Stay away - lesson learned for me, hope I can recover well so that I can take care of my kids."

For Weight Loss (Obesity/Overweight) "I am going through early menopause and have gained 30 lbs in a year. It's been impossible to lose weight. I started phentermine last week. I have anxiety and am VERY sensitive to medication, so I was a little worried. I started with half and felt jittery, but it subsided in an hour or so. I've had a lot of extra energy, and my mood has been better. I have experienced dry mouth and trouble sleeping, but have lost 4 pounds in a week! I plan to stay on the medication for 3 months until I reach 148!"

For Weight Loss (Obesity/Overweight) "I have been on Phentermine 37.5 now for a month. Prior to taking Phentermine, I have tried everything! Exercise (Tae Kwon Do, P90X *with trainer*, and Insanity *with trainer*), changed my diet, did everything I could to lose weight. Nothing helped! After finding out I had hypothyroid, Doc put me on some meds, and also put me on Phentermine 37.5. So after the one month of being on this, I have gone from 338 lbs to 311 lbs. At the beginning, the side effects were bad! Always felt drunk, sweat all the time, couldn't sleep, and ALWAYS *even now as I type this* having a dry mouth! I have no hunger and only know I am hungry when my stomach hurts. So, this works... just be ready for a roller coaster ride in the beginning. Good luck!"

For Weight Loss (Obesity/Overweight) "I was very hesitant at first to try this because of the side effects. I started with 1/3 tablet for the first week, then 1/2 tablet. I’m on day 12, still taking 1/2 tablet, and have lost 6 pounds. For the first 10 days, I didn’t sleep very well even with Benadryl and melatonin, but I am sleeping now that my body is adjusting. I’m taking Colace to offset the constipation. Other than that, it’s amazing. My appetite is reduced, I’m teaching my body how to fast intermittently. It gives me energy I haven’t had in years. I definitely recommend giving it a try if nothing else has worked. I would rate it a 10 if it didn’t have the sleep and constipation side effects. But, it’s totally worth it."

For Weight Loss (Obesity/Overweight) "I stopped taking after several doses. Terrible nervousness and anxiety. Difficult to concentrate at work and communicate thoughts clearly, insomnia, mouth and eyes constantly watering, angry feelings, depression, no desire to eat or do anything else. I get dizzy running on the treadmill. The doctor told me to take half a dose. It’s still terrible. After reading all the negative reviews with the same issues, I am throwing this in the garbage. FYI, I also am allergic to aspirin and have a similar reaction to Lipitor."

For Weight Loss (Obesity/Overweight) "I am 43 years old, started 4 weeks ago at 186 lbs, now at 171. Sticking with a low-calorie/low-carb diet. Getting in lots of cardio. The pill isn’t magic, it’s been a lot of work losing, keeping track of foods, finding time to exercise, and cook healthy meals for lunch and dinner. The pill has curbed my appetite and helped with focus and motivation. No side effects after the first week (insomnia, dry mouth). All around pleased with results but wonder if I could have done it without pills, seeing as I stated, it’s been a lot of work."

Phentermine for Weight Loss (Obesity/Overweight) "This is a very good diet pill. I have been able to lose 15 pounds fairly easily combining Adipex with the Atkins diet. I don't have cravings, my appetite is normal and doesn't drive me crazy all day. I've been taking Adipex for about 8 months now and have no side effects whatsoever. I did try the generic brand, which was made by a different company, and I did have the side effect of not being able to sleep. So I stick with the name brand."

For Weight Loss (Obesity/Overweight) "Over a 2-year period, I gained 75 pounds. I felt terrible. I started exercising 4 times a week for an hour and put myself on a strict diet, only to lose 2 pounds in 2 months, I was completely discouraged. 1 month ago, my doctor prescribed me phentermine and told me to start with 1/2 a pill a day until I felt comfortable taking the entire pill if I needed to. I have lost 16 pounds! At first, I got a little tired during the day, like my insides were on overdrive and my body couldn’t keep up with all the energy. I also didn’t sleep well the first 3 days, but I feel great now and I’m seeing results! I started to exercise every weekday for at least 1 hour. I stopped the strict diet and just have everything in moderation. I make sure I eat multiple small snacks during the day, if I don’t, I start to feel sick. I still go out to eat with my friends and family, I just bring home a few days' worth of leftovers to pick at. It’s definitely teaching me portion control."

For Weight Loss (Obesity/Overweight) "I was at 185, now 174!! So far, 11 lb down in a little less than two weeks.. super excited! My goal weight is 130-135. 185 is the most I've ever weighed.. I don't think I look it, but the scale doesn't lie! Lol. I've had a few symptoms so far... dry mouth lasts all day whether I chew gum or drink water. Insomnia is horrible, I can have three hours of sleep and be fine all day. I used to get really jittery and want to move around, but so far I haven't been super hyper like I was. Today I felt my hands and feet tingling, not bad though. I have also had a headache the past two days... which it may not even be from this, hopefully, it'll go away. I also would have hot flashes but then get cold. Overall, I'm just excited to see results!!"

Phentermine for Weight Loss (Obesity/Overweight) "Started Adipex 9/10/18. Female - 5’9, SW 202 lbs. I have always been thinner until steroids for arthritis over the years caused weight gain. Goal is 160 lbs. My monthly check-up at the doctor on 10/6 weighed in at 191 lbs. Today, 188 lbs. I know my diet is under what I should have, usually 700-900 calories a day, light exercise. More energetic. Curbed appetite. No eating after 5:30 supper, no sweets, chicken only for fast food (no fries). If I want a mid-day snack, it’s an apple with peanut butter. One cheat day, up to 1400 calories, water only. Have dry mouth and insomnia. Faster heartbeat when active. No rage feelings. Actually, great mood because of the energy and feeling proud of myself for losing. I will gain a little back as I will have to add more calories into my diet, but have the mindset to eat healthier, and hopefully losing the weight, I will be more energetic when off Adipex. Good luck to all."
