For Weight Loss: I started in May and lost a total of 20 pounds starting weight was 205 now is 185. My doctor wants me to get to 160. 25 pounds more to go. I don't really exercise but I'm on my feet all day. I take it sometimes in the morning if I know I'm going to have a busy day. If I'm not I take before work at 3 pm. Side effects dry mouth so I drink a lot of water, that really quinces my thirst but I'm using the bathroom a lot because of drinking so much. I don't eat that much and I try to stay away from sweets, soda, candy and Alcohol. So far so good. Good luck everyone.

For Weight Loss: Im 19 years old, 5'3, female. I started taking phentermine in January of 2014. Lost about 12 pounds that month; I went from 180-168. I didn't really exercise like I should've nor did I change my diet which I regret because a notice that the first time you take it, is the first time you drop the most weight. I bought some again on June 12. Starting weight 168 lbs. it's now June 18th weighing in at 163lbs. I work out about 3-4 times a week and started watching what I eat. I completely cut off fast food, sugary sweets, any type of chips, etc. That's 5 pounds in a week which is amazing and I've also lost inches! My goal is 140-145lbs.

For Weight Loss: I have been taking Adipex 37.5 mg for about a month now. Eating low carbs and more veggies and protein. I eat around 1,000 calories. 5'3" 144 pounds. So far I've lost about 11 pounds and 10". I walk 2 miles everyday. Side effects: dry mouth and constipation (off and on). I worry about the heart valve side effects I've read that other people have had from taking this but I'm hoping to just have to take it for another 2 months or so. I would like to get down to 125 pounds. I do find that the Adipex helps me during the day although I still get very hungry at night. But I fight it by drinking more water. Good luck to everyone in their weight loss.

For Obesity: I'm a 33 yr old female 5'2" and currently 241 pounds. I started working out 4-6 days a week starting beginning of May. On June 3rd my doctor prescribed me Phentermine 15mg capsules. I'm taking one every morning when I wake up. When I started the medication I weighed 251 pounds. So within two weeks I've lost 10 pounds. The pill has helped curb my appetite so I'm not as hungry all the time as before. I still get hungry and because I work out so often I make sure I'm eating a high protien low fat/carb diet. I use My Fitness Pal to track what I'm eating and can usually keep it under or at 1200 calories. I've had NO horrible side effects. The only thing I've suffered from is dry mouth which is easily corrected with water.

For Weight Loss: I had been so upset with myself and couldn't even look in the mirror without total let down after gaining a massive amount of weight within the last 2 years. I am 5'9" and as of 4 days ago I weighed in at 251. I begin phentermine on Tuesday and as of today (Saturday, 6/14/2014) I weigh 240 pounds! In 4 days I've dropped 11 pounds. I take 30 mg in the morning and I do feel jittery, nauseous and clammy here and there but I realize if I eat a few peanuts, peanut butter, apple slices..etc I feel much better. The pill definitely curbs my appetite the whole day and I force myself to eat and when I do it's very light. By dinner I am hungry and do eat what I want but my portions are smaller and smarter. I also have cut soda and sugary drinks.

For Weight Loss: I started taking the meds almost 2-weeks ago. Lost 3 pnds on the scale but my clothes are loose and that's what matters to me. Most people focus on that "magic" number but everyone needs to keep in mind that muscle weighs more than fat; therefore, if you're also working out you're building/toning muscle. I'm 5'5" @ 153 which had my doctor questioning why I was in her office. The first 2 days I had terrible headaches but believe they were withdrawals from completely cutting out caffiene & sugar both at the same time (wouldn't recommend). My appetite has been little to nothing so I have to force myself to eat. I'm continuously drinking water because of dry mouth but that's a good thing. Good luck and don't focus on the scale so much!

For Weight Loss: I took phentermine for 9 months losing close to 70 pounds (start weight 200 end weight 130) I was so happy with the results but.... As soon as I stopped taking it I gained all the weight back plus 10 pounds. My doctor prescribed it for me again but my body no longer responded to the medicine. That was my experience. I don't regret trying it.

For Weight Loss: I have been on a routine diet and exercise program for thirteen (13) months now. The phentermine has helped me tremendously. You cannot take it continously, however coming off for three (3) months as recommended, worked for me. I have lost sixty-six (66) pounds since I started taking this medication in July 2013. The first few months I tried diet and exercise alone with very little success. I have an under-active thyroid (hypothyroidism), and this medication has helped me with my success. I continue to control my diet and still go to the gym regularly, I have twenty-four pounds to go to get to my goal weight.

For Weight Loss: My weight loss experience with phentermine was successful. Early on, my doctor would refill with the agreement I would stop by every three - four weeks for a blood pressure check. Since my blood pressure was never an issue, and everything else was good, I continued on with the daily time-release capsule, 15 mg. Took a few days to get used to, but after that all was good. In six months I lost 15 pounds and am grateful it was slow and steady. I'm 5'5', weigh 137 pounds, and I feel good. I exercise, eat lots of vegetables, try to keep carbs to a minimum and I'm mindful of portion sizes. Phentermine worked for me. I highly recommend!

For Weight Loss: I've been on phentermine 37.5 for about 3 weeks all I can say is I love it! Not sure how much I've lost so far haven't weighed myself but I've noticed a huge difference in my clothes my tummy looks flatter my face slimmer, I dislike that I don't get hungry but I try eating lots of veggies/fruits throughout the day. I also drink tons of water. There's a lot of negative reviews with people saying they gained all their weight back more but let's be realistic if you're eating out the way you used to of course you are going to gain weight. This pill is supposed to help you change your bad eating habits, it works you just gotta put in work to! Hope this helped oh I forgot to mention I've had no side effects at all. Feel awesome.

For Obesity: I started taking Phentermine January 16, 2014 after 4 years of not losing and only gaining. Starting weight 238lbs, Current weight 192lbs. Very excited about the changes. Dr said I would eventually plateau and he would take me off. Some minor side effects but overall very happy. Definitely some more weight to lose but this gave me the encouragement I needed.

For Weight Loss: I started phentermine on May 1st 2014 lost 9 pounds the first week. It's hard to eat I'm never hungry so I need to start eating something healthy and small a few times a day. I have missed 5 pills this month but now on May 29th I'm down 13 pounds starting weight 189 now at 176 hoping it will continue to drop I'd like to be at 150.

For Weight Loss: Started 12 days ago at 231lbs., I have lost 11 lbs. No exercise, no cravings...its great! I take the pill 37.5 mg at 7 a,m so I sleep at night with no problems. I wish I would have tried this sooner rather than trying so many fad diets, wasting time. I feel in control of my eating for the first time in years, no more hitting the drive through on the way to & from work each day. Bonus...I have extra cash now that I am not going out all the time buying junk & snacks all day.

For Weight Loss: Today is day 18, I am not losing as rapidly as I was in the first week with a loss of 11 pounds total putting me at 196. I started at 207 I am now weighing in at 192.2. All the side effects are completely gone, I still have to make myself eat. I also go to the gym 3 to 5 times a week. Today I weighed in and went up 2 pounds not sure why I haven't "cheated" my diet. I find that the smart ones brand has desserts to help those with a sweet tooth and you are not totally killing your success. I hope to have better results coming in the near future.

For Weight Loss: I have been on this for about 2 weeks. The first 3 days were great. I had energy and very little appetite. I have lost a total of 5 lbs. I am on a 1200 calorie diet. Lots of water and veggies and fruit. I walk 1-2 miles a day. I have lost inches just wish it would go quicker. Ha ha. I was 308 and now 303. I want to be at 170. Guess it will take another year in a half or so.

For Weight Loss: Have been on it two weeks today. Starting weight 211 (I am 5'1" tall). I'm down nine pounds. Lost six of those the first week and three the second. Doing it in combination with a low-carb diet. Haven't exercised yet, but I'm thinking I better start. Side effects: dry mouth. At the start, I felt a little jittery and very talkative, but those side effects have subsided. No insomnia or racing heart. It has helped tremendously with my snacks and cravings. I am a nervous chewer and would snack all day long at work on sugary stuff and often wash it down with a soft drink. Now, I drink water at work and have one snack (usually an Atkins bar or other low sugar product), and I get through just fine. No gnawing hunger pangs.

For Weight Loss: The first month from 179 lbs down to 161lbs= 15 mg the whole time. Now using 30 mg and the first 8 days. From 161 lbs to 154lbs. It would make me very happy if I can make it the next 3 weeks down to 145 lbs. Then I have prescription for 37mg the last month. If I will make it down to 130 lbs in June, well I can't ask for more.

For Obesity: I have been taking Phentermine (30mg) for 5 weeks now and I am down 10lbs! Slow and steady! I've been overweight my whole life, have tried every kind of diet plan out there. I know how to cook healthy, I know about portion control, I know exercise is key....but I just needed that little something to keep me on track and phentermine is it! I read a lot of other reviews on here and those who are saying that they gained all the weight back once they stopped, I can guarantee they were not eating healthy while taking this medication. YOU HAVE TO EAT! This has really helped with my snacking and when I do eat I don't feel like I have to eat the entire plate. THIS ISN'T A MAGIC PILL- you have to eat right and exercise!! Good Luck!

For Obesity: Started phentermine 5/15, weighed 251lbs. Today is 5/21 and I'm down to 245lbs. I have to make myself eat. My energy level is fantastic. I used to take naps during the day, now I'm out in the yard working or cleaning up around the house. The only problem I have is sleeping, for the past two nights I literally have not slept. So, I think I'm going to take 1/2 pill tomorrow and see how that works. I'll post again soon.

For Weight Loss: I started taking 37.5 mg Phentermine 3/2014 and it is now 5/2014. In the past two months I have lost almost 40lbs!. my starting weight was 185 and I am now at 148. I went from a size 14 to an almost 6!! In the beginning I had severe dry mouth. but it has now subsided. I also haven't had any sleeping problems nor blood pressure issues at all. For anyone needing a jump start to weight loss and something to help you make better food choices this medicine is awesome!

For Obesity: I have been on Phentermine for 66 days, take 37.5 mg/day, and lost 10 lbs. However as of tomorrow I will stop taking it. It has caused a very negative change in my thoughts & personality & causes huge mood swings. After being on it for 2 weeks I started noticing I was super sensitive, however blamed it on PMS at the time. It hasn't gotten better though. I have been irritable, angry, restless, & just general feelings of sadness. The past couple days I also have been noticing "flashes" of something dark on the floor out of the corner of my eye but when I look in that direction nothing is there. When I read these are rare side effects I decided I need to stop taking it.
