"I started Phentermine 30 mcg on Friday, May 20, 2016. Although I was prescribed 2 pills a day, I only take one because I hate not being able to sleep at night. The first night I only got three hours sleep (but was not tired the next day). In 6 days I went from 171 to 164. I have limited my food intake but I haven't exercised (aside from weedwacking the yard). I do take one generic tylenol pm before bed so I can sleep. I have a dry mouth, but it isn't bad. I am calm and focused so overall, it is a pretty good experience so far. I am a 53 year old female with a thyroid that doesn't function very well and I'm 5'2". I had a hip replacement last year and I need to lose weight because each pound I gain is 3 pounds of pressure on new hip."

"I started taking Phentermine in March of 2016. As of my doctors visit on 05/16/16, I have lost a total 23 lbs. My starting weight was 289 and I'm currently 268lbs. The medicine does cause dry mouth, but after taking it for sometime it doesn't seem to bother me. I gained most of my weight after having my daughter who is now 4 years old. I decided to change my eating habits before taking the Phentermine. It has become a lot easier that way. My goal weight is 185. I will keep everyone posted as I continue this weight loss journey."

Adipex-P (phentermine): "In Jan of this year I weighed 170.0. I had some gallbladder issues that ended up with it being taken out and caused some weight gain. It is now May and my last weigh in was 141.4. I love my adipex and I would recommend it for anyone. I have had two children and so my body has been through the ringer. I love the energy it gives me and the appetite suppression. I also like that it makes you thirsty and the only thing that helps is water. I am now a water drinker and I drink well over the daily recommendation. I love this!!"

Adipex-P (phentermine): "Been on generic adipex for 1 month. Start weight 183. Current weight 171. Drink lots of water on this. Dehydration can cause headaches ( get migraines already so this did not increase due to the medication). First day i was nauseous. first week was extreme dry mouth and complete lack of appetite. I had to remind myself to eat during the first week. At some point during the second week i was feeling a bit hungry but not the constant hunger i experienced before. As of the end of the first month the only persisting side effect if the dry mouth. I'm also not sleeping very well! but I just take tylenol pm for that. overall i feel good. i'm losing weight. im less hungry so i'm selecting better food choices. (chocoholic lol) and no serious issues."

"Well I only lost 4 pounds in 2 weeks with diet and exercise but maybe I'm adding muscle with all the energy I'm putting into the gym. I can only hope, otherwise, I could've lost 4lbs on my own. Does wonders for my mood, energy level (most of the time) and appetite suppressant. Will give it the full 3 months and re-evaluate. Just a little disappointed I've only lost 4 lbs in 2 weeks with a complete overhaul in diet & exercise and this pill."

"I started taking this a little over 3 weeks ago, the first couple of weeks I had lost 6 pounds, no cravings or hunger whatsoever, but a few days ago, all of a sudden the cravings came back and my hunger, I've hit a plateau, and like I said I'm starting to get back to my old eating habits, hopefully this is only temporary and the better results come back soon.."

Adipex-P (phentermine): "I have been taking generic Adipex since Dec. 2015. I am 5 food tall and was 211 pounds. The first 11 pounds came off quick. Then I got down to 195. Now I am back up to 200 and can't drop the weight. My energy level is a lot better though. I don't really eat that much. So maybe my body is holding on to what I do eat. Who knows."

"In January of 2015 I weighed 285lbs. at 5 foot 7 inches. I do have high blood pressure.I started a weight loss challenge and in 3 months with dieting and exercise I lost about 30lbs. I continued the same regimen and by February of 2016 I was 238. I seemed to have hit a wall. On recommendation from my doctor I started phentermine 37.5 in the beginning of March.As of May 14, I weighed 228lbs. The medications does give dry mouth and your energy is increased. I have about 20 days before the end of 3 months on the meds and will seem my Doctor then to see what she recommends further. My goal weight is 210. I am 50 years old.1992 when I graduated Police Academy in the best shape on my life I weighed 200lbs. I want to get near that and maintain it"

"I started phentermine 37.5 on 5-4-16 with a weight of 247 lbs and as of today 5-11-16 I'm at 235 lbs. All I want is WATER! I have zero cravings for sweets or sodas. I keep my carbs at 100 a day. Only side effects I have are increase in energy and dry mouth, which is why I always have a bottle of water in my hands."

"I started Phentermine end of October of 2015 and ran on my treadmill 2x a day. I got hurt and wasn't able to workout for about 2 months. It is now May 2016 and I only take Phentermine every other day and I lift weights 2x a day and I have went from 227lbs. Xl shirts, and a size 18/20 in pants to now 166lbs. Medium shirts, and a size 10 in pants. I only drink water unless we go to the movies I'll share a sprite with my daughter. Drink smooties and eat a nutri grain bar for breakfast. Skip lunch and eat dinner with my kids before 6 most of the time. I LOVE IT!! I'm also on a anti depressant that makes me gain weight so I'm doing pretty good at keeping it off and losing more."

"I started taking the phentermine pill with a water pill on 03/28/2016. its now 05/06/2016 and I'm down 23 lbs. I am proud of myself but I was hoping for a bigger result. I also exercise 6-7 days a week at the gym and 4 days a week outside with a personal trainer and have a strict diet. I'm hoping that maybe I'm gaining muscle weight along with losing weight and that's why I haven't seen more results. I will keep you guys posted!! Good luck on your weight loss journey!! :)"

"I have been on Adipex/Phentermine 37.5 mg on and off for years. I have found that Adipex seems to work very well the first few weeks, but for me it does stop working. I think it's a good idea to stop taking it for a few days to a week and then start it again. I have adhd and have noticed that Adipex also helps me focus more than anything, although it's not approved for add/adhd. As far as rating Adipex for weight loss, I feel it is an excellent medication. I have never had any side effects from Adipex!"

"Started phentermine 37.5 April 7 2016. I'm 31 yrs old 5'1" my start weight was 154lbs. I have struggled to lose weight for about a year. I had no self control to my sweet and fatty food cravings. I wad spending about an hour at the gym 4 days a week and i was still gaining weight. Today I am 139pound. The medication helps me with my cravings and portion control. I only speed walk for about 30minutes 4x a week. I am so happy! I drop 15pounds!"

"I started 37.5mg today (was afraid to start because I was afraid of the "upper" aspect) but finally did. I'm not sure of my weight but I feel "blobby". I ordered a scale today and will update this but wanted the first say it has a limited upper effect. Nothing like I expected. Smooth, energized, and even helped my mood. I'm looking forward to results as I'm going home to work out now!"
