For Obesity: "I took phen 37.5 early 2016 and lost almost 35-40 pounds. Felt really great but then my doc asked me to stop taking it. Now in last six months I've gained everything back! Starting my phen from today again! But feeling too dizzy and nauseous. Hope this won't last for long...Good Luck everyone!"

For Weight Loss: "Started 2.20.17. Biggest side effect is lack of sleep. I notice I am not crazy about food as before. I cannot tolerate any caffeine including chocolate as my heart rate will increase. Looking forward to results!"

For Weight Loss: "Started phentermine February 15th weighing in at 183 as of today February 21st for my first week I'm at an even 170. I'm 26yrs old and 5'8! Only side effect is dry mouth.

For Obesity: "It's been a week on the meds. I am loving it. Little dry mouth. But no other side effects. I've lost 7lbs. I've been to the gym almost everyday. Eating low calorie diet. It definitely gives you energy. BP has been good. I have been checking it at least 3x a day. I'm only planning on being on meds for 6 months. I hope it doesn't take longer than that to get to goal."

Adipex-P (phentermine) for Weight Loss: "I started phentermine capsules end of August 2016 weight was about 197-199lbs starting out. I tried to lose weight for 2 years I had never been this heavy & felt miserable everyday cut out pop was drinking only water & attempted to diet with no success. Tried the tablets before 37.5 mg gained 10lbs so this time my primary doctor called in capsules to the pharmacy, within the first week I lost around 7lbs which I'm sure was water weight. First month I lost 25lbs give or take then the 2nd month I didn't lose so I went off of them for 2 weeks started again lost a couple more lbs. I am now 165lbs Feb. 2017 I haven't lost since but I have maintained. I also never exercised. 500 calories the first 3 weeks on them with breaks here & there."

For Obesity: "I started this medicine on November 4, 2016. I weighed 286 pounds, stood 5'5". This was the heaviest I have ever been. As of today, 2/20/17, I'm down to 194. I have more energy now then before. My cravings have changed so much. At the beginning, it was bad. Couldn't eat more then 2 or 3 french fries. No caffiene. Felt dizzy, light headed, and just plain weird. That only lasted a week or two. I eat normal food, just so much less, and not the same rubbish I used to. Food does taste different, but it's for the better. I don't crave sweets, or fried foods. I'm so happy with the way I am now, and am still taking it."

Fastin (phentermine) for Weight Loss: "I suffer from obsessive compulsive personality disorder. It makes me not want to be around other people so I stay in all the time, which leads to extreme lethargy. I just lay in bed all day and spiral downward until I have no energy to do anything at all. Fastin gives me the energy psychologically as well as physically to get out of bed and start doing things. It does cause some side effects, but these are to be expected with something that works so powerfully. Only this or Zoloft have helped me to lead a productive life. With doctors for zoloft, I have to make appointments, pay for insurance, a doctor visit, the prescription, and wait in line at the pharmacy, none of which I can do after I run out of medication. Thank you Fastin"

For Obesity: "Started Phentermine in September 2016. My starting weight was 248. I'm 5FT 7IN and 37 years old. I am 5 months into Phentermine and my current weight 2/18/17 is 199. I feel that most reviews on here are from people who have recently started so I could share my experience and give a longer perspective. I will be brutally honest as I'm not looking to sugar coat anything. The first week taking Phentermine is horrible. You feel light headed, dizzy, memory loss, sweating, heart pounding, shortness of breath, energy and other symptoms. However, after about a week, these symptoms stop. Stay with it. This will change your life with the right attitude."

For Weight Loss: "I am 28, 5 ft 7in and my starting weight was 298lbs. I have always looked smaller than I weighed. I started taking phentermine 01/19/2017. I work out every other day for four hours. I mostly do cardio between treadmill, elliptical, stair climber, and arc trainer. Depending on the day I will only use two different cardio machines. Then utilize the weight lifting machines to tighten and tone. Had my first weigh in yesterday and I was down 20.8 lbs. My goal was 10. This has def helped me get my eating under control and I have more energy as well. The only problem I face is severe dry mouth which water will fix or even chewing gum. I would recommend this as a starting point to lose weight. I didn't get a refill as per my request."

For Obesity: "At age 54, taking this is the only way I've been able to lose weight. I used to be able to lose 10 to 20 pounds pretty easily with just better food choices and mild exercise. But over the last several years with a strict Paleo diet and exercising five days a week, three days a week with a trainer, I Wasn't able to drop a single pound. As you get older you must consume a depressingly small amount of food in order to lose weight, this drug gives you the willpower to stay with a low cal a day diet. For me it's impossible to shop and cook and only consume my low cal per day. So, I used prepared food services like eat fit go and factor 75 to be certain of the calories I'm consuming with no leftovers and no snacking during cooking."

For Obesity: "Started taking the 37.5mg pill 2/4/17. I'm 5'5 Weighing 251lbs which is why I'm considered obese. I now weigh in at 240lbs without exercise or eating healthy. I also tried "tenuate" it didn't work for me which is why I'm currently using this pill. I have no negative effects that I can report besides dry mouth. I see people say they still eat food. What I am experiencing is "not wanting any food at all" only fluid. I tried to eat some lamb and rice and vomited. Thats one of my favorite foods to eat. I have no true urge to eat food only fruits. Which I like. My Dr. told me not to worry just make sure I stay hydrated so don't get headaches."

For Weight Loss: "Start weight: 246lbs at doctor on 2/01/2017. Started taking Phentermine 37.5 on 2/02/17 (Friday). Went to the beach that night, came back Wednesday and weighed 242lbs (at doctor). I ate grilled chicken salads and one or two chocolate chip granola bars a day and drank lots of water. While on vacation I walked a lot since I was at the beach sight seeing, did some shopping and just did normal vacation stuff. I didn't workout while I was gone. Today is 2/12/2017 and according to my scales I weigh 240lbs (scales are dialed up 3lbs to match doctors). Since I've been back from vacation I've worked out 7 mins every day and went walking, slow pace. I eat salads and granola bars still and sometimes have a heavier dinner. Mental side effects exp."

For Weight Loss: "I started Phentermine on January 13, 2017 as of today February 11, 2017 I have lost 16 pounds. I have not worked out at all. Ive been eating a salad at 11:00 and 3 chicken stripes with ranch and chic fa la sauce from Chic fa la for dinner everynight. I lost 9 pounds my first week, 5 pounds my second week, and 2 pound my third week. I didnt lose any week during my last week probably because I cheated almost everyday. 261 to 245 so far. Wish me luck on my next bottle."

For Weight Loss: "When prescribed, I really didn't think this was going to work. I have pretty much been overweight my entire life. My doctor reccomend I take phentermine, mainly because diabetes was in my family history. December 31st, weighing 263, I began to take half of a 37.5 tablet. The first day, I was super dizzy for the first few hours. But I never felt that sensation again. I haven't really felt any symptoms related to the pill. Today I went in for my weigh in, and I weighed 246, so a totally lose of 17 pounds in 42 days. Although I wish it were a larger weight loss, I do have to take into consideration that I haven't really exercises. But my diet has changed radically. I would recommend to give it a chance. You never know what could happen."

Adipex-P (phentermine) for Weight Loss: "I'm 19, female 240 pounds and 5'8" I started taking adipex yesterday (02/10/2017 and I had a boost of energy for about 5 hours along with constantly sweating, dizzy, no appetite I had to force myself to eat and my heart racing and blurry vision here and there. I sure do hope to see results because these side effects are pretty terrible. Any recommendations? I'm drinking lots of water and eating with the pill."

For Obesity: "This medicine has helped me so much. I've lost 40 pounds in the past year with no change in diet or exsersize. It decreases my appetite and gives me the energy I need to interact with people throughout the day. Worked almost like an anti-depressant for me. Couldn not be happier!"
