Phentermine for Weight Loss (Obesity/Overweight) "Day 4, taking 1/2 tablet of the 37.5 mg. Decreased appetite, more energy, some dry mouth here and there. I've noticed at some times a decrease in concentration, like a foggy feeling. Nothing too bad, but a little off my baseline. Haven't weighed since day 1. Hoping to lose 15 lbs this month. I like that I don't feel 'cracked out,' but I am hesitant to up my dosage yet. I'll keep taking the 1/2 tab until I get really used to it. Once I reach my GW, I plan to wean myself off in the same way. Will update."

Phentermine for Weight Loss (Obesity/Overweight) "My doctor prescribed Adipex on Oct 5th, 2012. I was at 287 lb, 5'8", and 57 years old, struggling to lose any weight but nothing. Together with the Adipex, my doctor gave me other instructions, like what to eat and also to exercise. I have had no kind of side effect unless you call no appetite a side effect. I make sure that I eat at least 1,200 calories daily. I also exercise for 1 hour and 10 minutes every day, 7 days per week, no excuses, no nonsense. I find that when you make up your mind and heart, everything was good. I’m at 236 lb, I have the energy of a 25-year-old, I’m looking better and feeling better. Soon I’ll reach my goal of 180 lb. Feb 23, 2012."

For Weight Loss (Obesity/Overweight) "This medication made me go from 210 pounds to 150, and all I did was take it. I hate to say it, but I was lazy with this medication, I didn't even work out or eat healthy. However, without even doing so, I managed to lose weight and keep a good amount off. Granted, I wasn't very hungry while on this medication, as it makes you lose your hunger drive, but I started noticing changes within the first week. By the first month, I had already lost 15-20 pounds and maybe 10 each month after that, as it began to get harder because I had less weight to lose."

For Weight Loss (Obesity/Overweight) "I started Adipex, generic phentermine 37, on Tuesday, 9/20/16, at like 6 pm. First mistake... so I was up all night, literally. I didn't sleep, actually, I haven't slept more than a couple of hours at night all week. Definitely lots of side effects: heart beats abnormally sometimes. I also feel very alert. I took my 2nd dose on 9/23/2016 in the morning. Starting weight was 223 lbs, I'm at 213 today, 9/26/2016, so I lost 10 lbs in 6 days. I get nauseous by the smell of most foods, I can barely eat. I have absolutely no appetite. I have major constipation, but I'm losing weight, though. So my ultimate goal is 160. This is my 2nd time on the medicine, and I lost about 30 lbs the first time back in 2012, so wish me luck. I will try and update again soon."

For Weight Loss (Obesity/Overweight) "This is my second time around with Phentermine 37.5 mg. 5 years ago, I lost 38 lbs in 5 weeks. I stayed on a high-protein, low-carb diet (chicken, chicken, and more chicken) and 1 pill a day, with 1 cheat meal a week. Unfortunately, I gained the weight back because of self-stupidity. I started again on 4/5/16 with Phentermine once a day with a B12 vitamin concoction injection once a week at weigh-in at the doctor's office. This time, I'm adding cardio, swimming, and weight training 4 days a week. I experienced no side effects, I have no appetite, cravings, and lots of energy. I take my pill after breakfast, about 11:30/noon, to ward off the late-night snack attacks and still allow me to go to bed around 11 pm. I highly recommend this medication."

Phentermine for Weight Loss (Obesity/Overweight) "The first day I took this medicine, I had so much energy and was extremely focused. The second day was a little different (I am prescribed the dosage of 37.5 mg/day). The second day, my appetite was gone all day, and toward the later afternoon, I started throwing up. I could not eat any food that day. Now comes day three, I take the medicine again, hoping that I wouldn't have the same reaction as the day before, and I was right, but everything worsened. I still haven't gotten my appetite back, and I've thrown up seven times today and cannot hold any water or anything down without throwing up two minutes later. I haven't had food in two days because of the constant nausea and vomiting. If you have a sensitive stomach, beware."

For Weight Loss (Obesity/Overweight) "I started Adipex in 2006, weighing in at 215 lbs and used it for 2 months, got down to 185 lbs, which is less than 30 lbs. I stopped taking it and gained 15 lbs, give or take. I started it again 2 days ago at 196 lbs and weighed in today at 189 lbs. The positive thing is I crave water, and since I am never hungry, I eat healthy because I don't want to eat anything."

For Weight Loss (Obesity/Overweight) "I'm a 52-year-old woman, moderately active through golfing and walking, and a relatively healthy eater who never has dieted and didn't need to. Menopause, age, activity level, and metabolism have each contributed to a 35-40 lbs weight gain. After a year of increased activity and reduction of calories and carbs such as pasta, potatoes, and breads, I was not able to really maintain a 5-10 lbs weight loss if I didn't walk at least 5 miles each day. I noticed there was an overall reduction in energy. My doctor had been on this journey with me; food journals to now Phen. 37.5 mg. In 12 days, I've lost 8.6 lbs. I do have a dry mouth and a suppressed appetite, which I hope over the 3-month prescription will help me to reduce portions considerably."

I have a lot of energy and have been able to do a lot. I have been going to bed earlier, but I can't sleep past 4:30am. I also seem to need to catnap about 2:00 p.m."

For Weight Loss (Obesity/Overweight) "I'm 5'2" and 245 lbs. Never suffered from being overweight in my life, but in the past couple of years, my weight has been progressively going up, and I work out and diet is extremely modified, so my doctor decided to try me on this medication. I started it last Friday, 11/15, at 245 lbs, and as of today, I'm 231 lbs. Meaning 14 lbs in 6 days. My appetite has definitely been suppressed, really not much of an appetite at all, but for the most part, the medication is doing what I desired it to do, and besides last night only getting a couple of hours of sleep and up the remaining of the night, I feel good. Will post again after a month or so."

For Weight Loss (Obesity/Overweight) "I just started taking the pill on July 23, and I weigh 178. Today is July 26, and I now weigh 174. If you have dry mouth, try chewing sugar-free gum. As a singer, I use that trick all the time to keep my mouth moist, and it works. Please drink lots of water as well, but it makes the dry mouth not so bad. I have a thyroid condition, so I take that pill early in the morning, and I make myself eat a piece of toast or something 30 minutes later and take the pill, and I don't have a problem sleeping at night. I walk every other day, and I have a decrease in my appetite, but I still eat. Some people say that I don't eat at all, that is not healthy. Oh, and I don't drink or eat anything with caffeine, so I won't have a problem sleeping at night with the meds."

For Weight Loss (Obesity/Overweight) "This is my third day taking phentermine. The first day I felt great (increased energy, good feeling, and suppressed appetite). The second and third day of taking phentermine. I do not have increased energy. I only have suppressed appetite. I am drinking a lot of water and no caffeine. I am unsure why I cannot obtain that energy. I would like some increased energy because it does motivate you to become more active."

For Weight Loss (Obesity/Overweight) "I am 61.5 inches and I weighed 179 at the first Dr. apt. For 41 years old, that is not a good place to be, but with the medication, I am hoping to drop 30 - 40 pounds. First day, I had absolutely no appetite, was awake longer than normal, but I did finally sleep. Day 2, I still had no appetite, but I did force myself to eat a little bit. Easier of a time sleeping, still up later than I wished, but once I fell asleep, I was out. Today is day 3, and I weighed myself, and I am down to 173 lbs, 6 pounds in 3 days. I am ecstatic! I have been exercising by doing Zumba and lifting weights. It is amazing to me how much energy I have. I can do an hour of Zumba. I sweat like crazy, so you need to remember to drink a lot of water. Hope to meet my goal in no time."

For Weight Loss (Obesity/Overweight) "I started phentermine 37.5 mg on 7/10/15. I was 230 lbs. It's now 7/30/15, and I've lost 17 lbs in 20 days! I have not exercised at all. I only drink water or milk. Cut out all sugar, and I don't even miss it. This pill really kills my appetite. When I do eat, it's always something healthy, but very small portions. I'm not hungry at all. I still have about 60 lbs to lose. I hope it keeps going this easily."

For Weight Loss (Obesity/Overweight) "I have used Phentermine after both of my babies to lose the baby weight. The first time I lost 30 pounds in 5 months. This time it has only been 8 days, and I've already lost 11 pounds! I have never experienced any negative side effects, I am thirsty and drink a ton of water. I have zero appetite, so I have to force myself to eat, but I also feel energized, focused, and extremely happy while on Phentermine. I always recommend this to my mommy friends who want to lose their baby weight as well."

For Weight Loss (Obesity/Overweight) "Began taking the 37.5 mg version on 2/23/14, and I've lost 7.8 pounds in 6 days--tomorrow will be one week. I've gone to the gym 5 of the 6 days for 50 minutes of elliptical workout. I've been eating just under 500 calories a day, and I have to make myself eat because food doesn't seem appealing at all--it's the weirdest thing. I take my pill at 11 a.m. and have no trouble falling asleep around 10:15 p.m. Will post again next week with more details. I'm 5'7" (and 1/2) and started my diet at 191.6 pounds."

Phentermine for Weight Loss (Obesity/Overweight) "I started taking this pill because being on depo and an office job has caused me to gain a ton of weight. I will update weekly. Because the first week I have seen a huge change. My energy is back. I don't want to sleep all the time. My focus is back. And I am driven. I have cut out all pop, started watching the calorie intake, and I am actually pulling my kids in a wagon every night. We have now extended our walk, and I feel great. Starting weight - 6/20/17 - 324 1 week weight - 6/28/17 - 317 (-7 lbs)!!! I could not be happier, and I know I am living a healthier lifestyle. Without this med, I don't think I would be able to do it. It suppresses my appetite and boosts my energy. Good luck to all."

For Weight Loss (Obesity/Overweight) "I have been taking phentermine for only about 4 days now. But I have lost 8 pounds. I am also taking another pill for depression and anxiety for about a month, so I'm not sure if all my side effects are from only phentermine, but I have been having lots. I have been unable to sleep for more than a couple of hours a night, a migraine on day 3 that sent me home and put me in bed all day, little to no appetite, irritability, and diarrhea for a day now. However, I've been reading that these side effects only last for a week in some people, so I'm going to wait and see. The weight loss part is working so far. I've just had to force myself to eat food throughout the day. If this drug works, it will be worth it."

For Weight Loss (Obesity/Overweight) "First time I took phentermine years back, I lost 40 lbs in 2 months; starting weight was 189. In about 3-4 months, later went down to 129 lbs. I had no appetite; I would have to force myself to eat. The pounds came off so rapidly, people thought I was sick. Now back on it again after gaining it all back after 8 years' time. Now started phentermine again about 3 weeks ago, weighed 213, now down to 195. It really works! And first-time users get better results because it's not as effective as it was the first time, but still works."

For Weight Loss (Obesity/Overweight) "F 5'2 SW: 173.3 lb Oct 3, CW: 166.8 lb Oct 7 GW: 150-145 lb. I decided to take phentermine 37.5. After doing research, I scheduled an appointment at a local weight loss clinic. After being evaluated, I was given the okay to take it with a 1200 cal low-carb daily meal plan. I was instructed to take half the pill for 4-7 days, then 1 tab daily in the AM on an empty stomach. I did 2 days half pill and 3rd day full tablet. I work out 2 days with a trainer and 4-5 days on my own a week. In 4 days, down 7 lbs!!!! Wow, right. Amazing curbing of my appetite, but because I'm working out daily, I still get all cal in daily. I also drink 3-4 liters of water daily (a must). I plan on only taking for 30 days and working out 40-60 min daily. I'll update with final weight after 30d."

For Weight Loss (Obesity/Overweight) "I was on phentermine for almost 2 months. I started out weighing 175 pounds and now I am at 155.50. I started out with bad headaches, numbness of feet, cold feet, tingling legs, and no appetite. I am a 38-year-old female. I was recently seen at the doctor's office. I went in for my monthly checkup, I was feeling sick, my head was hurting bad, and I was short of breath. I complained of my feet being numb and my legs feeling tingly. I was immediately taken off the medication. My heart was beating irregularly, they said this was a reaction to the medicine and I was feeling sick because my heart was beating irregularly. I was admitted from the doctor's office to the emergency room. I will now be seeing a heart specialist to see if there's any permanent damage."

I started taking Adipex yesterday (02/10/2017), and I had a boost of energy for about 5 hours, along with constantly sweating, dizziness, no appetite. I had to force myself to eat, and my heart racing and blurry vision here and there. I sure do hope to see results because these side effects are pretty terrible. Any recommendations? I'm drinking lots of water and eating with the pill."

I felt a little jittery yesterday when I started and hardly had any appetite. I had to remind myself to eat, but I did eat less. This is day two with no jittery feeling and lots of energy. I feel really good today, drinking lots of water as it is making me really thirsty. I am feeling hopeful that this is what I needed to lose weight. I feel like it is already working since I am eating less, and I have started a mild exercise."
