Adipex-P (phentermine) for Weight Loss: "I've been on Adipex for 12 days now and haven't lost any weight. The first week taking the medicine gave me so much energy and no bad side effects. I'm not really sure why I haven't dropped weight since this pill has stopped all my cravings and I've been eating so much less food. I've been making all my meals at home and only have eaten out maybe once or twice. I also maybe only have a glass of wine once a week. I'm 5'5 and weight 160 pounds. I would like to get back down to 140-145. I haven't been exercising...do you think that's the problem??"

For Weight Loss: "I started 10/16/17 with a starting weight of 245lb. Today, not quite 5 weeks later I am 221. 24lbs lost in less than 5 weeks with min exercise (20 min walk 2-3 times a week). I have noticed the weight loss slowing down a little and will begin working with a trainer 4 times a week on Monday. Negative side effects for me have been dry mouth (just means I'm drinking more water!) and constipation. Unfortunately, my provider would only like me to take the medication for 12 weeks, I know other providers who have prescribed for 6 months. I hope I can talk her into it!"

Adipex-P (phentermine) for Weight Loss: "I started Adapex P for weight loss I'm 5"1 and 202 pound and I'm 44 years old. I have lost 46 pounds in my own this past summer and gained 15lb back so I started the Adapex today I'm really thirsty which is good because I have drank 4 bottles of water today! I'm NOT HUNGRY at all but I did eat some but couldn't finish a turkey sandwich lol. I had a lot of energy and felt happy I have had a really bad week so feeling this good was really good .I have taken this before maybe 10 years ago and did really well I wore a side 22 pants and in a year was down to a side 12. So I'm hoping I do as well this time .Good Luck Ya"ll !!"

For Weight Loss: "I started taking phentermine 37.5mg October 18, 2017 once a day. I initially weighed in at 211lb on the date I started taking the medication. As of today November 18, 2017 I have lost 20lbs. I am down to 190lbs!!! I have completely changed my eating habits to no red meats, fried foods, starches, and I try to keep my calorie count right at 1425 per day which was difficult at first but now its much easier. I don't drink soda of coffee anymore but I'm super thirsty all the time. The first weekend I took the medication it made me very jittery and I suffered from insomnia and horrible headaches. After the first four days of being on the medication my symptoms improved and eventually went away. I would recommend starting this medication on a weekend."

Lomaira (phentermine) for Weight Loss: "I tried to lose weight with diet and exercise for years. Doctor first put me on an expensive medication and it worked but I didn't want to pay $200 a month! doc told me about lomaira and how it could be used to target eating in the afternoon and reduce my exposure to too much medicine. So far so good. No bad side effects and my appetite is definitely lower. I'm taking one tablet in the morning and a second before lunch."

For Weight Loss: "As I mentioned in Part 1, the phentermine gave me so much ENERGY. I began cleaning my entire house. The only side affect I remember was a very dry throat. I've only been on the pill for 4 days. I went to bed that night. I woke up with a rapid heartbeat. It scared me. I knew it was the phentermine. After the 2nd day, I haven't had any more rapid heartbeats waking me up out of my sleep. The pill causing me to drink more water than I usually do.(LOVE IT) I got on the scale today. SW 180lbs Nov. 8, 2017. CW 175lbs Nov. 11, 2017. It really decrease my appetite. I haven't started exercising yet. I'm just eating smaller portions."

For Obesity: "Went to a weight lost clinic and paid 30 dollars for a consultation for the pills for a two week trial and did research and found out I could get them from my regular doctor and asked my regular doctor to put me on them and he did with a 30 day supply. I started the pills on 11/5/2017 I’ll keep you guys posted with a update next week Also I go to the gym 4 times a week and changed my eating habits. S/n I took the pills about two years ago from another clinic which they gave me the 37.5mg and water pills and a fat burner as well with a b12 shot and my weight fell off and like 2 months the pills work"

For Weight Loss: "Phentermine gave me ulcerative colitis. Started taking them at the age of 32. A diet doctor gave them to me. Within a few months my life had changed. Always had to go to the bathroom. Ruined my life. Now I am taking pills. Have to see my Gastroenterologist doctor every few months. Also have to have a colonoscopy every three years to make sure the pills are working."

Adipex-P (phentermine) for Weight Loss: "I have always been up and down with my weight, but never to the point where you look at yourself in the mirror and don't know who you are looking at any more. Well!!! I have reached that point where I said "ENOUGH IS ENOUGH" I tried working out and eating well, a personal trainer, fasting, pills, diets and a lot more. You name it, I tried it! Well 6 weeks ago I decided to give Adipex-P along with B12 & Methionine Inositol Choline (MIC) Injections injections a try. Guess what? I have lost 26 pounds. I cant explain how amazing this feels... IT WORKS! The 1st week alone I lost 8 pounds and I didn't even work out. The only side effect I got is Dry mouth which is good b/c it keep you drinking water. Once you see it works you will keep going b/c you feel motivated. Good Luck :) & GBU"

For Obesity: "Started this medicine 30mg once a day in the morning before breakfast. Great appetite suppressant. The side affects for me a bit much. The first week the dry mouth was annoying and I was drinking more than 64 oz of water daily. I felt high and out of my mind " loopy" "disoriented " "dazed" throughout the day. Then I'd have moments of Heat Waves, like it was having a HOT FLASH ( turned 47 on Friday)! Insomnia, mood swings, and sweating as well. The side effects are awful for me AWFUL, however the results are AMAZING. I'm done 14 lbs in 14 days n would probably be more if I didn't celebrate my birthday n eat my dinner n have a drink. My blood pressure has increased being on this medication n now have to go on a low dose BP pill!"

For Weight Loss: "I was diagnosed with Hashimoto's Thyroiditis in 2012, 3 years after they realized my thyroid was out of wack. Progressively I have gained and gained weight, I am now 30lbs heavier than I was 9 months pregnant. I have other health issues that make me somewhat of a doctor's nightmare, or a puzzle they can't find all the pieces too. This is the start of trying to bring my weight down (my GW is 145) and that's about 80lbs. It's Saturday Nov 4, 2017, dose 1, 37.5MG, took my BP first, will check again in an hour and before bed. Wish me luck! The nurse at my PCP's office is also on it, I was hesitant and had not filled my script right away, she has lost 13lbs in 4 weeks ... so, what do I have to lose? The weight!"

Adipex-P (phentermine) for Weight Loss: "First day on adipex...I weigh in at 245 pound's, I'm 33 and 5'7. I tried adipex 2 yrs ago when I was at my heaviest which was 286. I lost a ton of weight, I went down to 215 and was super happy. I went through a lot in my life and became depressed and gained 1/2 of the weight back. I can tell you if you want to loose the weight you have to diet and exercise, I was going to the gym 3 to 5 times a week 2 yrs ago before the major stuff happened in my life. I am starting my new journey today and couldn't be happier about it. My doctor put me on adipex-p and topiramate to help with my weight loss program. I don't start the topiramate until next week so I'll let you guys know how both of them work."

For Weight Loss: "Female, 19 y/o. Started Phentermine 37.5 mg tab. on October 17, 2017 with a weight of 217lb. Today makes 18 days I’ve been on the medicine. My current weight is 202lb. This medicine is genius. I completely shut out soda, fried foods (with the exception of 2 cheat days)and any kind of candy, chocolates. I found that eating an hour after I take the medication helps me stay fuller longer (I take it every morning at 7). I drink a lot of water a day. I really haven’t exercised at all and have managed to drop 15 pounds! This medication really helps. Eating right and drinking a lot of water did it for me!!"

Adipex-P (phentermine) for Obesity: "I’m so envious of those of you that this worked on! I have completed 2 months of this pill daily and nothing. I did get some side effects the first week (faster heart rate, jittery, dry mouth, muscle clenching) and felt I was eating less but clearly not. I still feel just as hungry and I’m on the 37.5mg dose! My dr told me to take a pill and a half to see if that helps and so far it has not . I am so depressed as my eating is out of control I am literally always hungry which is why I needed help with the pill in the first place. I just wish I’d had the luck you all have had."

For Weight Loss: "My doctor prescribed me with phentermine 37.5mg. I've recently just started the medicine yesterday on 10/25/2017 and so far I have jitters, a little dry mouth, I'm full of energy, and I have no appetite! The good thing is I feel like I can run a marathon race. I drink plenty of water a day and portion my food intake. I plan on eating healthier and working out daily. My starting weight is 265lb. I plan on going back to my college weight which was 188lb. I'm excited for this journey and to keep you guys updated."

Adipex-P (phentermine) for Weight Loss: "Hey guys checking in again. So when I started I was 198 and now I weigh 145 !!!! This pill is simply amazing!! I’m closer to my goal weight which is 130! If you’ve been reading my previous reviews you’ll know everything!!! I still have the blurry vision but that’s it. And it comes and goes now. Also. I skip the pill some days, so that I can see if I can eat good without it. And I do well. Bcuz I’m a min I won’t qualify to take it anymore. So if you’re having doubts. I say DONT doubt!! Take it and watch the weight FALL!!!! I’ll check back in when I’m off it guys :)"

For Weight Loss: "I've been on Phentermine for about two months now. SW: 200lb and my CW: 174lb. I hope to get to 160 by the time I finish the medication. Thanks to the drug, I've been staying away from "bad foods" and I am working out more. I try to stay under 1200 calories a day and I am successful 80% of the time. I try to work out at least 5 days a week, mostly by walking briskly 30min-1hr, and sometimes cardio (like dancing and jump roping) and strength training (like squats and planking) combined. With the medication, you feel like everything is possible, and it gives you the energy to get out and do things. I have to say, the medication does begin to wane after the first month - you have to make a lifestyle change in order to lose more and maintain. GL!"
