For Weight Loss: "I recently was given phenteramine 37.5 mg; When going on family vacations in Mexico, I always covered up by the pool and never attempt to venture into the ocean, embarrassed of what I looked like in a bathing suit. It is an Awful feeling being 42 y/o with 2 girls and not enjoying vacation. I am currently 200, and today is day 3. I haven't seen any movement on the scale yet. I have been well under 1200 calories with lots of lemon water, 2L daily. I am always on the go, walking due to my job. I realize it is only day 3, should I have seen some loss?"

For Weight Loss: "I am a 42 years old woman who is 5'6 and 242 lbs. I took Phentermine 37.5 two years ago and lost 30 lbs i(started off at 243 and ended at 213 and went back to 248 over the next 2 years). At the time I was also on a strict eating plan and I was working out 4x a week. Well since then I had stopped working out because work and grad school was hectic. Two weeks ago, I decided to change my eating habits, do a cleanse and detox and I have lost 6lbs. Yesterday, I started my pills again and some cardio on the treadmill. I WANT OUT OF THE 200s!!! (even though the charts says a 5'6 woman should be 118-154 but I can not see myself that small)! I am so ready to take control of my health and my body!!"

For Weight Loss: "I started taking phentermine 3 days ago and I am already down 5 pounds following the 1200 calorie diet that was given to me. I am 5'9 started at 217lbs. Now 212. Also I am 30 years old. I was thin most of my life until I lost all controlled of my eating while pregnant. I also have a history of depression and anxiety, and I actually feel better on the phentermine. No anxiety attacks and feeling very happy. It seems to be working well. The prescribing doctor did tell me that it is very important to keep up on the water no less then 8 bottles a day. Maybe those having trouble losing will find this helps them. Good luck to all!"

For Weight Loss: "Jan 1 I told myself I have to start making healthier food decisions I started working out 30 mins each day and eating healthier. Got on the scale after a week and didn't drop any weight. I had an upcoming apt1/11/17 and told my dr what was going on. She suggested pherntermine 37.5mg. I started taking phentermine 1/12/17 my morning weight was 181.2. Today is 1/14/17 and my morning weight is 177.6 . I felt a little jittery the first day I noticed when I ate right after it was not as bad . I do have cotton mouth all day which I feel is a great side effect because it makes me drink lots of water . I have a 24 oz cup and I have been filling it up at least 5/6x daily .goal weight is 150. I will post on 1/20/17."

For Weight Loss: "I wasn't technically "Overweight" in most books, but was about 30 lbs more than I was a couple of years ago. At age 37, I was 5'8" and hovering around 200 lbs. I was not happy at all...my clothes weren't fitting, and I wasn't getting results at the gym. Couple that with my bad habit of meeting buddies for happy hour almost daily, and boom- there I was. I told my doctor about this, and he put me on 37.5mg phentermine. I couldn't tell a difference at first, but slowly I noticed I didn't crave that cheeseburger, I didn't binge eat out of boredom...in fact, I didn't even think about it. I've been taking the medicine daily for about 2 months, and have gone from 200 lbs to 181. Diet and exercise are key...great medicine!"

For Weight Loss: "Started 15mg 5/1/17 aged 25 5"8 start weight 16.0 now 15.6 so one week in I've lost 8lbs, very happy no side effects apart from a dry mouth. Hasn't affected me mentally at all. Only thing that has ever curbed my cravings and snackin habits. I can quiet easily eat under 1000 cals a day and be satisfied, which never would of been possible before. Don't ever feel hungry and find myself eating smaller portions, and will eating some carbs to. Feeling positive!"

Fastin (phentermine) for Weight Loss: "I heard from a lady I work with about Fastin and she told me it worked well for her. So I came on this site and read the reviews. I was concerned with a lot of reviews stating that the were side effects such as pounding/racing heart and jitters. Dospite the reviews, I still ordered the pills. After receiving the pills, I still waited a few days before starting because I was terrified of the side effects. So I finally started taking the pills a week ago. I started taking just half a pill in the morning and half after lunch like recommended in a review I read. After a couple days I began taking a whole pill after breakfast and a whole after lunch. I have had no side effects at all and have lost 5 lbs in 1 week"

For Weight Loss: "I began taking phentermine on Thursday December 29th, 2016 and on January 6th, 2017 I went from 201 to 189. I have not been exercising (I usually did 4-5 times per week, but stopped right before christmas) and I am amazed at how energized, and healthy I feel. The first couple of days I did have some chest pressure, but working in a cardiologist office I think it was mostly in my head. My insurance did not cover the medication but there were quite a few coupon options out there. I will keep yall updated on my progress!"

For Weight Loss: "I started taking Phentermine Friday January 6 2017. I take half a pill for a week. Then a while one starting this upcoming week. So far it's been 3 days I have amazing energy, I have not felt jittery at all. I have been eating healthy. Usually when I am trying to loose weight I see what others are eating and I think oh dang just one bite lol. With this medicine I have no cravings. My tummy growls some but I will grab a Apple or a orange and I am satisfied. With each child I have (3) I kept gaining weight. I am 252 I am so upset at that. 2017 holds a new future for me and my family. This medicine has given me hope I feel so different. I do have yukky mouth sometimes but I keep mints and it makes me drink more water. Good luck to you all"

For Weight Loss: "I am a 44yr old woman. 4'11" starting weight 169. I started on Dec 26 only taking a half dose of the 37.5 mg. I did this about a week. The first few days I experienced insomnia and faster heart beat but it didn't last long. I have lost 4lbs. The first week I was still eating more than I expected but now it seems to be holding longer throughout the day. I am drinking a lot of water. Partially because I have extreme dry mouth. I just started at the gym as well so I'm hoping for some really good results in the coming weeks. I will continue this and keep updating. PS One side effect I have noticed a significant change in, is loss of libido. I hope this is not a lengthy side effect. :("

For Obesity: "I took phentermine and counted carbs, exercised, lost about 30 lbs, but after 5 or six months, no changes. Dr said stop. My weight had been creeping back up About a year later (or more) & I decided to try finishing the bottle, it was expiring. 37.5 mg, x 38 days, lost another 4-5 lbs. It has taken me 4 weeks to get reapproved from insurance. Had anyone else had success after stopping when it no longer works then starting again?"

For Weight Loss: "I took phenermine 2 years ago, and within the first month I lost 36 pounds and not a flabby loss. I was weighing in at 283 6' 1" and 30 days later on my check up I weighed in @ 247. I ran 6 miles on the elliptical and still did my body workouts. I had just quit smoking and cut my calorie intake to 1800 per day. At the end of three months I weighed in @ 229. The only side effects I had were cotton mouth and constipation but that's because I didn't drink a lot of water. It's a great pill to help you get to your goal, also Lets just say the wife was pleased!!! I hope this helps you achieve what you are looking for!!!!!"

For Weight Loss: "I started Phentermine on October 8th 2016 at 273 lbs (yap I said 273). That day was the lowest I've ever felt. I cried and my Dr. asked why I'm crying. Really at that weight he had to ask. So he prescribed Phentermine and today January 2nd 2017 I'm happy to say I now weigh 239. A loss of 34 lbs. This is the only thing that has worked for me. I can't THANK my Dr. enough. Here's to a healthier happier 2017."

For Weight Loss: "Phentermine has worked very well for me. Started on the medication around Thanksgiving and I have lost 18 lbs. That is a lot considering that I started at 150 lbs and I am 5'4". I wanted to get off about 20 lbs that I had gained through menopause. My appetite was out if control. My doctor recommended a low carbohydrate diet because I was insulin resistant. Basically, I am eating chicken, fish, beef, ham and turkey that is somewhat low fat. I still cook my chicken in a little bit of olive oil. I also put a small amount of butter on veggies. No sugar, bread, pasta, potatoes or rice. Read carb levels on salad dressings or sauces. My goal is to eat no more than 20 carbs per day. Drink a lot of water!"

For Weight Loss: "I started Phertermine 37.5 mg 12/20/16 @8am and just felt light headed, insomnia for the first 4 nights and seemed to forget things during working hours, now it is 12/29/16 and insomnia has decreased, cotton mouth since day one and constipation are increasing though. I haven't been able to exercise yet, due to knee pain. But meal portions are very small, and lots of water intake at least 2 liters a day. Initial weight: 193 right now at 186. Will keep you posted"
