For Weight Loss: "I have lost 80 lbs using phentermine for almost 10 months. it has been a great thing for me. I have energy to workout and have had no desire for soda in almost a year. I take it every other month and it is still working for me. I have a few friends of mine that are taking it as well and it has worked for them as well."

For Weight Loss: "I started on 8/8/15 at 257lbs, tomorrow will be 2 weeks I have been on it and I'm down to 240lbs, that's down 17lbs!! I work out 4 to 5 times a week, walking 3 miles or the elliptical for 45 mins. I have cut out all sweets as I noticed foods with a lot of sugar make me shaking while one the pills. I have like no appetite, but make myself eat at least 3 times a day, I mostly eat fruits and veggies when I do eat. I drink about 8 bottles of water a day due to dry mouth and excessive sweating when working out. I have only found 2 side effects dry mouth and constipation which I take a stool softener every morning to help with."

For Weight Loss: "I'm on day 6 of phentermine, only taking half of the 37.5 and start my whole pill tomorrow. So far so good, I don't have a ton of energy but I'm having to force myself to eat because I have no interest in food (which is really new for me). I am down 6 lbs in 6 days and am yet to hit the gym, I am following a low cal diet from my nutritionist. The only down fall is I have a really hard time getting to sleep, BUT I wake up feeling like I got a ton of sleep so either way."

For Obesity: "I'm 39 yrs old 5'6" & 239.4lbs. I just started Adipex-P 8 days ago-- 8/12/15. The 1st day I had so much energy I couldn't contain myself. That has calmed down. I drink way more water than I use too. I find that it helps with the dry mouth and chewing gum as well. I have NOT weighed myself yet.. a little scared too. But I will on day 10. My goal is to loose at least 50 lbs . 175-180 seem to be a good weight for me. I feel super small at that size. I lost 70 lbs on my own about 3 years ago. I was 256 at my heaviest. I don't exercise at ALL. Just being honest. Severe PAD doesn't allow for much of that. I have 2 mths on this. SO EXCITED!!!"

For Weight Loss: "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 his medication, i didn't even work out or wat healthy. However, without even doing so, I managed to loose 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 Obesity: "For 7yrs I have been fighting edema that pitted, I could push my finger in my leg over a half a inch. Went to several specialists, had everything in my body tested, checked, scanned and probed, I was miserable! 20lbs or more of water weight, that made me gain more weight due to trying to fight the water weight. Several diuretics pills, I still take 2 that still did not remove all the edema. I asked my doctor about Apex due to all the weight gain, since all medical test were good including my heart, he agreed. I was given phentermine 37.5, I noticed the first week, my legs, face and body loss of the edema!! I been on this, quipril, and hydrochloride and I have lost over 35lbs, feel great, I no longer have pain from the pressure of the water"

For Obesity: "Started on phentermine in June I have lost 17 lbs. This really curbs my appetite . I do experience some side effects . These are tolerable such as dry mouth and constipation. I drink plenty of water. Also eating plenty of veggies really helps . I do not crave any sweets or junk food. This med is great if you are overweight. Has helped with overeating and indulgence."

For Weight Loss: "I started phentermine 30mg on 8-4-15. So far I have gone from 129 to 120. I'm loving how fast the weight is coming off, but I don't really have any increased energy I was hoping to have. However, the weight is coming off and my appetite is suppressed so I guess it's doing its job. Hoping for the next 51 pounds to come off just as fast!"

For Weight Loss: "I started Phen. About theee weeks ago. Starting weight was 186lbs and im 5"6. Currently im weighing 171lbs. I love my results!! I can see a difference in my clothes already. Im not exercising yet, but i plan to start . Dry mouth is the only con. I also realized in week one that when i took a whole pill in the morning I found myself very hungry in the evening right before bedtime. The trick i learned was to take a half pill with breakfast and another half with a early lunch to keep my appetite surpressed all day."

For Weight Loss: "The first day taking a whole pill before breakfast made me feel tingly and jitter the whole day. That I could handle if it meant I would lose weight and curb my appetite. However the deal breaking side effect was the extremely red, itchy rash on my face that started on the second day. My tongue was also beginning to swell and I had a weird feeling in my chest. I'm disappointed in myself for having these side effect because I was very hopeful that this medication would work for me."

For Weight Loss: "I began taking Phentermine on June 20th and have lost 12 pounds so far with it. The first week made me feel really weird and slightly jittery but that went away after the first week on it. The only bad side effect I get from this medication is severe dry mouth. Sometimes this is good because it makes me drink more water than I normally would however, sometimes this medication makes me not thirsty at all. I do believe that my body is getting used to it because recently I will take it and still feel hungry. I have lost the weight with the medication, exercising and eating relatively healthy. Overall I like this medication and I do believe it has jump started my weight loss journey."

Phentercot (phentermine) for Weight Loss: "Doctor prescribed a month ago. Today is my first follow-up and I lost 14 lbs. Initially, dry mouth, insomnia, and slight headache plagued me. But after about 5 days, all of that subsided. I only eat chicken, turkey, and white fish, veggies and fruit while working out for at least an hour, 4 days per week. After a cup of black coffee in the morning, the only other drink all day is water. I hope the progress continues.....goal is to lose 40 lbs and keep it off this time!"

For Weight Loss: "I have been on phentermine 37.5 for 44 days, have another 46 to go (90 day supply). I started out at 305. I have been walking every other day for 2-3 miles, eating only fruits/vegetable throughout day- then a normal dinner (even pizza/burgers). After 44 days, I'm down to 274, with eating a relatively normal diet. With the dry mouth, I drink more water, been feeling great, sleeping good, as long as I take the pill first thing in the morning!"
