For Weight Loss: "Today is my first day taking it. 7/29/15. I am a 22 year old female and weigh 270. I have exercised and ate clean plenty of time where I would lose about 20 pounds each time but would lose motivation and gain it all back plus more. I asked my doctor about this after being on qysmia last year and hearing some friends talk about it. I take a half of pill in the am before breakfast and the other half between 1pm & 2pm. I didn't have any headaches or nausea. I was very energized all day at work. No dry mouth so far either. I'm going to check every week and see where I am at. I know its no miracle pill but the doctor said it would be a great JumpStart to a new me. By the way I have already changed my eating habits before starting this."

For Obesity: "I started taking Phentermine 37.5 on July 19, 2015 (265 pounds) on the morning of July 27, 2015 I lost 9 pounds, in just one week. That's amazing to me. I start to get jittery when I forget to eat, in which I try to eat healthy foods, chicken, fish, turkey, veggie's and fruit at least 3 times a day. It's very important and helpful to drink plenty of water, also chewing gums helps. The one side affect for me is constipation. My goal is to get to 175 and maintain it. Best of Luck to Us ALL."

For Obesity: "Started taking Phentermine 30mg on Saturday 7/18/15 and its now Tuesday 7/21/15 and I was beginning to think my scale was broken because so it days I've lost almost 8 pounds in just 3 days.. Started at 214lbs now at 205.4lbs.. Seems like alot of people on this site say they have had similar weight loss on it. I'm just hoping the weight loss continues to quickly fall off, I've been only drinking water, cut out pop completely, drink only one cup of coffee In the morning and limit my diet to less than 500 calories. Seems to be working:)"

For Weight Loss: "Started July 11th, 2015- 5'5'' tall and 197lbs. Today is July 21st, 2015 and I weighed in at the gym this morning at 186.7- so slightly over 10lbs in 11days. First few days I had extra energy. The first full week I was exhausted and did not go to the gym. I had really lowered my caloric intake and cut out all extra sugars, breaded carbs and dairy...I ate a little more over the past weekend and this morning I finally felt up to exercising. I still feel tired, but fall asleep for an hour after work and then am ready for bed by 10p. I am not super hungry, but still try to avoid being around my favorite "junky" foods because I overeat just because it's in front of me... I take 1 30mg pill daily and got a b12 shot, which I can repeat 1x month."

For Weight Loss: "I started Phentermine 7-11-15. I have been at a stalled weight for the past year and a half and then all of a sudden gained 15lbs in a week along with other symptoms I was having. Went to the doc and did blood tests, everything came back healthy. I'm 6'1 female and weighed 203. I weighed myself this morning on 7-20-15 and am at 193lbs. The side effects I have is dry mouth and helps drinking a lot of water and chewing gum. Doctor put me on this for 3 months to jump start my metabolism again. So I'm hoping once I'm done the weight stays off. I work out 5 days a week and do cardio 4days and eat 4-5 small meals a day. Nothing else worked. I tried lots of different fat burners and NOTHING helped til I got on phentermine."

For Obesity: "I am about to finish my second month on phentermine and I am down 32 pounds! I feel great! The worst thing is the constant dry mouth, and taste in my mouth I constantly have, and I have no desire to ever drink. But I have a question for anyone else that is on this, has anyone else experienced serious mood swings, or just a complete behavioral Change in yourself? Since I have started this medication everything seems to annoy me or piss me off?! Kind of weird but I figured I would ask to see if anyone else was experiencing the same change?!"

For Weight Loss: "Im a 54 year old male, 5 11" 300 lbs. Been taking it for 3 months; lost 30 lbs. Have lots of energy for yard work and exercise. I was a compulsive eater, but now I can walk by donuts with no pain. made progress eating better and less. I Take it first thing with water, then don't eat till late afternoon. Seems to reduce my desire to eat. Makes me appreciate lighter foods over heavy foods. I have more physical and mental energy. Only negative is makes it a little harder to sleep. Its actually possible, some day I will not be the fattest guy I know."

For Weight Loss: "This medication really does work. I am on my second round of Adipex (generic). The first time I took it I was 297pounds. I lost 30 pounds in 12 weeks with no exercise at all. I ate what I wanted although I did not have much of an appetite at all. I ate 3 small meals and two snacks daily. I did make sure to drink at least 6 glasses of water per day and I drank a protein drink in the morning. My energy level was great. However, when it was time to be off of the medication, some of the weight came back. It is important to exercise and reduce calories while not on the drug in order to maintain the weight loss. My suggestion would be to start healthier habits while on the medication. It will help in the long run."

For Weight Loss: "I'm praying I have similar success to some of these stories I've read. I just started Phentermine 37.5 mg today, 7/10/15. I'm 44, 5'2" and 229 lbs. So far, I feel great today. A little bit revved up, but not too bad. Absolutely no hunger at all. Very thirsty - but that's a good reason to slam water instead of soda. I'm giving up all sugary foods and drinks. I want to get back to my comfortable weight of 130-140, and then see where it goes from there. FINGERS CROSSED! I will update more in a couple days. Good luck to all!"

Fastin (phentermine) for Weight Loss: "I started taking this pill when I was 218lbs and I now weight 135 lbs! I had thyroid issues too that originally caused the weight. But once managed I still had a hard time getting the weight off. This pill literally changed my life! Yes it does speed up your heart, my dr did an ekg before hand to make sure it was safe to take. But the results are beyond worth it. And if you take it with water or juice and a banana, you'll be good to go until dinner time! It took roughly 6 months tops to lose the weight, and I've maintained the weight loss for about 3 years now. I still fluctuate a little due to my thyroid. But I just start back on it if I need to lose again."

Adipex-P (phentermine) for Weight Loss: "I went on 4/28/15 and as shocked when I weighed in at 189, I'm 5'7". My walking around weight is typically around 170-175. I started Adipex and went back in June for my check up, I'm down to 174 with steel toes and long sleeve. I was told to avoid the generic and only Adipex, with a coupon it is $50. The energy boost is great, not too much...just don't take one after about 4 or 5 pm. Now, the interesting part...My weight gain was due to consuming alcohol on an almost daily basis...the Adipex supressed my appetite AND supressed my desire to consume alcohol. I can attribute this to the supression effects of the drug and the dry mouth gives you the desire to drink water or a sports drink."

For Weight Loss: "OK ladies (and gentleman) I cannot believe this I LOST 13LBS IN 5 days. I started When 6-29-15 weighing 269.. I went to the doctor 7-3-15 and weighed 256 (no way).. Im still in shock.. My husband is so scared because he never seen anything like it. I completely changed the way I eat.. I only eat grilled or baked foods, fruits and lots of water with lemon (my skin is now amazing). I eliminated everything that's not clean. I removed fast food, soda, salts, sweets basically everything that was killing me slowly. The appetite suppression is amazing and allows me to make better and healthier decisions.. I have had side effects but they are starting to subside. I do not own the a scale but my clothes are getting very lose."

For Weight Loss: "I started taking phentermine, and it did give me headaches and shaking, but I found if I break the pill in half, I don't have the bad side effects. I also have lost about 17 lbs. In the last 30 days. So it is working went from 201 to 184. I wish everyone the best of luck. BTW I did not change my diet or exercise plan. My doctor will only put me on this for 21 days. Because after that time it stops working. So I take a half a pill everyday every other month. I have lost about 50 lbs altogether on this in the last 6 months doing it this way."
