For Weight Loss: "50 yr old woman, 5'6"...last weigh in: 206 lbs. I had gastric bypass surgery in Feb. 2009 and within a year lost over 90 lbs. I kept the weight off and maintained well until 2012 when I started school full time while also working full time. I was eating on the run for 2 1/2 years ..gained 40 lbs. I started phentermine this morning and omg! The energy!! My plan is to exercise 3 days a week, stick to a moderate meal plan (I made a list of DON'T EATs) and drink a gallon of water a day. I want to get rid of those 40 lbs and maintain a healthy way of eating. I'll post again when I weigh in on 10/8. I have a feeling my clothes are going to tell the story before then. I'm excited!! Good luck everyone."

For Obesity: "I started on phentermine 37.5 on 9/19 today is 9/26 and I am down exactly 10 pounds. I did exercise 7 days for 1hour each since being on this medication. Nothing very strenuous. I ride the bicycle and put it on interval training. I started at 279 and currently weigh 269. Target weight is 190. I do under 25 fat grams a day and try to target 1000 calories max. I've unfortunately had a couple of cheat moments Ughh and wonder what o would have lost if I didn't have those! Just wanted to share what adding exercise has done for me. I want this weight off so I can be more mobile and play with my kids!!"

For Weight Loss: "I have been taking the 15mg dosage and I have to say that through all of the dieting products and programs that I have been on, this drug has really helped me the most. I see that a lot of the people start out on the 37.5mg, but my doctor asked me if it was my first time taking phentermine and that if it was then he was going to start me off on the lower dosage because the side effects can be a little much at first, and then if need be, he'll take the dosage up. Its been 1 month (8/23-9/23) and I've lost 15 pounds( 294-279). I increased my cardio and started weight lifting and went "cold turkey" on bread, rice, pasta and potatoes. I'm loving the results and the fact that my cravings are now controlled."

For Weight Loss: "Today was my 1st day taking this pill. I will post again soon to see what happens. I have to lose about 20 lbs before trying to get pregnant. I weigh about 225lbs, due to injury and inability to vigorously exercise. But I will also begin my at home chair routine today as well to see if this works. So far this pill causes me to be sleepy and a bit loopy, and I'm drinking lots of water."

For Weight Loss: "This is the second time I have gone on Phentermine 37.5 mg. I took it back in 2013 on and off for 3-4 months and lost about 22 pounds. I am 5'2" and weighed about 156 when I started, 134 when complete. My big mistake after going off it was to start eating like I did before starting. Being menopausal, it's so easy to eat whatever looks good. My best advice to everyone is to remember that once you go off of it, you HAVE to alter your old eating habits or you will have wasted your time. Now I'm back on it again this year, almost done now. This time I went from 153 in April to 128 now, and I'm going to work hard to stay there. My worst side effects both times were dry mouth and constipation."

For Obesity: "I started Phentermine August 13, 2016. I did 1/2 pill for 7 days and then started with a whole pill there after. I do have issues falling asleep before 1 AM with no sleep aid. However, once I take my pill at 6 AM the following morning, I'm super energized anyway. The first week I did get the mid day crash. One day I experienced racing heart. Dry mouth daily until I drink at least 120 oz of water. I went for my follow up appointment on September 13, 2016 and I lost 11 lbs. I have not been exercising but I do move around more. I have had a partial hysterectomy and I feel like it has affected my ability to lose weight. This month I will be incorporating weights and home exercises."

Adipex-P (phentermine) for Weight Loss: "I'm 5'5" 240 lbs. after years of exercise and dieting I just could not seem to lose more than a few pounds. My doctor and I decided I should try Adipex. I just started taking it yesterday (9/15/16). I've noticed a few side effects even just with the first dose. I have a bit of a dry mouth and it has caused insomnia, and a bit of jitteriness too. Granted it was my first pill so I'm hoping these will subside after a few days. It has curbed my appetite and I've noticed an increase in energy. Now I'm not sure if it was due to the medication, but by 5/6:00 I started to feel like I was crashing a little bit. I don't want to give this a rating yet being as I just started, so I will update at a later time."

For Weight Loss: "I started to take this drug for weight loss after being wounded in the middle east, the extra weight from hospital stays were just too much on my replaced part. I took the medicine a little over a year cycling off and on with ekg etc under my doctors super visionice, well needless to say the last few months I have been having all kinds of weird problems, complete numbness in my legs to the point I could not feel cuts deep cuts, I started to lose balance continuous falls and progressing symptoms,(ie. Memory loss, urinating on myself, clumsiness) the list is enormous. So to make this review a bit shorter, after going blind in one eye from optic neuritis, and losing the ability to walk I was image, and an LP I have MS and leasions all over."

For Obesity: "I'm a 40yr old mother of 1, struggling with weight loss. In the beginning of the year, I entered a biggest loser challenge. From January to March I lost a total of 14lbs by diet and exercise. I started off and 214lbs and by march I was 200lbs. I did lots of cardio using a beachbody at home workout called "Cize" with Shaun T. Well I plateaud and got discouraged. I also started to go back to me old eating habits. Guess what I gained it all back by August. Weighing 213lbs On August 29 I started phentermine 37.5. I take my pill at 5am and I'm currently down 5lbs in one week. I also do at least 45 min cardio, drinks lots of water and watch my calorie in take. The side affects have also subsided. I can sleep now"

For Weight Loss: "This is my second round with Phentermine. When I took it about 2 years ago, I dropped 17 pounds in 4 weeks; felt super energized and worked out. About 3 weeks ago, I was tired of being tired again and went back to the doc to get back on phentermine. I have to say, that, while I had struggled with yo-yo dieting and emotional eating, plus being really active versus super lazy for quite a while now. Long story short, this is week 3, I have lost 10 pounds (5 ft 3, started at 157.8, down to 147.8), am doing nooo emotional eating whatsoever, feel energized, often have to remind myself to eat, eat way healthier again, and have started exercising yesterday again. I just know, I will keep it up this time and get down to 120."

For Weight Loss: "My doctor prescribed Phenteramine 37.5mg the last week of April 2016. I have always eaten healthy but not enough time to live in the gym and hectic work schedule it's almost impossible. I started off weighing 267 lbs it was higher than that but couldn't get it to go any lower. It's almost four months later and I am down to 243 that's only 24lbs I was hoping to have lost a lot more than that from reading other post. I am not letting that discourage me I am making healthy life choices for permanent weight loss. I go back to see my doctor in a few weeks for a follow up and cool off period. Wish me luck."
