"I started phentermine 37.5 on August 29th at 199lbs. I saw my doctor today for the first month checkup on September 29th at 184 lbs. Lost 15 lbs since medication, and more than 20 lbs since my highest weight of 207lbs. Doctor said the medication was working really well for me, and will prescribe me another medication for maintenance after the refills are done. I've been trying to stay under 1200 calories per day, and added some brisk walking 5-6 days a week for 30min-hour. This medication really helps to curb your appetite and to make better choices when eating. I don't have any side effects other than occasional dry mouth, and since I take this medication first thing when I get to work (8:30am), I have not had any sleeping issues."

Adipex-P (phentermine): "I took adipex in August of 2015. Starting weight 232lb. Lost 16lbs the first month and got off the pill. I kept up my workout routine and lost and additional 17lbs the following month. I kept the weight off until December 2016. Well its September 26, 2017 and I'm back up to 230lbs. Today is my first day back on Adipex. I plan to eat better, drink more water and exercise a lot more than I did the first time to get better results!!! So excited. My goal weight is 175lbs.... wish me luck!"

"I started Phentermine 15mg in August 2016 (I weighed 274 lbs), by Dec 2016 I had lost 50 lbs. I attended kickboxing class too and changed my eating habits. I felt good about myself. Until I noticed some Hair loss. I was told that was not a side effect. I stopped the d Phentermine & the kickboxing after about a month, my hair stopped falling out. After 3 months I returned to the Phentermine, guess what ? My hair started falling out. I kept the weight off until August when I began my bad habits and not working out. I blame that on my knee injury, lol. I am now looking for another med to get me going again. I recently had a knee replacement and waiting for the day I can go back to kickboxing . Phentermine is only intended for 3 months"

"So I started taking phentermine because I have bad knees and cannot exercise and without losing weight I can't have surgery for a knee replacement. I must admit I was very skeptical about this pill but so far so good. I am 41 yrs old and I started taking this pill August 28th 2017 and at that time I weighed 365 lbs and as of this morning Sept 2nd I weigh 353 lbs. Thats a total of 12 lbs in less than a week. It completely takes my hunger away and I do have the dry mouth but I will deal with that. I have cut my food in half as I feel full much quicker and I like that. So far so good. I do drive a school bus so loading and unloading wheel chairs is a work out by it self so I get some exercise just not like I would like due to my knees."

Adipex-P (phentermine): "Today is day 7 taking it. Only lost one pound so far, but it might be giving me a little bit of extra energy. I am 60 so maybe it takes longer to take effect in post menopausal women, idk. I am 205 and 5'5" so hoping to lose 50 lbs. I will keep a positive attitude and hope it kicks in better soon."

"I started taking this medication on 08/22/17, my starting weight was 195 lbs. now I'm at 190 and it's only been 3 days! I only drink water! About 6-8 16oz bottles a day, I eat about 1200-1500 calories a day. I have a lot of green veggies, and added a protein bar and meal replacement shake to my day. I take half a pill when I wake up and the other half around 4pm with my lunch. It helps by dividing the energy so I don't crash. Side effects are that I can't really fall asleep 100%, but I'm not tired so I'm pretty fine. My blood sugars have been way better! I'm a type 2 diabetic. So I take less insulin now. I work out 2Xs a day, 15 min. Sessions of just at home workouts nothing crazy, I just make sure I get my heart rate up and sweat like crazy"

"I am in my mid 20s. I weigh 204 and I am 5'3. Today on 8/17/17 is my first day taking this pill. I took it two hours after breakfast which was around 10am. At least 2 hours later I started to feel weird, not a bad weird either. I just felt alert, awake and so energize that I shake if I'm sitting still. I don't mind it at all because I'm usually sluggish and tired. I had a small lunch and I feel completely satisfied, which is crazy. I'm trying to be optimistic about this process that I'm doing because I do need my lifestyle to improve. We all deserve to be happy in someway or form. At the moment, the size and look of my body has stopped me from living. I hope this will give me a kick start to change. I will keep you updated! Wish me luck"

"I have been taking phentermine for a week now, and I feel much better. It has curbed my appetite and I am not sleeping as much. I used to be so tired all day. I am feeling a little discouraged however, because I have seen all these reviews of people losing like 7 pounds in a week/two weeks. I have not lost even one pound so far, even on an 800 calorie diet. I am hoping that after a couple more weeks I see a difference. I may update in the future if I remember!"

"I've started on Phentermine 11 Aug 2017 with a starting weight at 295.4lb. Today, 14 Aug 2017 I weigh 293.0 lb. I've started back walking a mile on my break at work. I will start working out at home for an hr, 3-4 days a week. Let's see what happens. I am so tired of this weight. I have let myself go. I know how to eat healthy, but have just let other things get in the way. Now my mind is set and I am ready for the new me."

"Aj - 5'8 - 283LBS After 4 yrs of obesity, 3 of them during my ex's (children's father) horrendous battle w/cancer & recent death, here I am. My family doctor was witness to this emotional journey and my physical decline with weight gain, extreme fatigue and body aches. I had a recent checkup and learned my bloodwork and specialist appt were all clear. I mentioned to Dr. A that I finally feel like I am seeing myself again and wish I could get my body to match my level of happiness and will to do more. He talked to me about Phentermine. After some thought I started on 8/5/17, one 30mg pill daily. Today I am -10lbs! No side effects and sleep well! I "plan" healthy snacks as my appetite is very low. Energy level is up but not crazy."

Adipex-P (phentermine): "One month today went to Dr for refill. Down 16 pounds!! I do waitress so that helps constantly walking at work. Adipex just keeps me from constantly thinking about food. First couple days restless can't sleep...learn to take it first thing in the morning so by bed time its ok."

My doctor said I should be eating 1,000 calories a day, exercise 4-5 days a week the 1st month, not eat breads, pasta, tortilla, fast food, Many carbohydrates, also supposedly eat less than 30g of protein a day.

"I started taking Phentermine on June 23. My starting weight was 278 lbs. My one month check up I was 264, and today I'm 259. I take a pill first thing in the morning and I get a boost of energy. I noticed if I take late in the day I have insomnia so if I forget to take the pill in the morning I wait until the next day. This pill has curbed my appetite a lot. This definitely helped with my weight loss. I have not been exercising so this weight loss so far has been by the pill and my deceased appetite."

Adipex-P (phentermine): "Well, I am back for my one month results. Starting weight 6/20/17 - 324. Today's weight -297. That's right!!! 27 lbs!!!. I have started to watch my calorie intake, I walk 3 -4 days with my kids, then the other days I am at the gym doing cardio and toning. I stopped drinking pop. I am up to a gallon and half of water a day. I cut the carbs way back. I have tons of energy, I feel great and everyone tells me that they see so much of a change in my appearance. I would recommend this to anyone, as long as you are looking for a lifestyle change. Not just a quick weight loss. (I have had friends who took it for fast weight loss, lost half the weight I have and gained it all back when they stopped)! This is meant to help with changing your life."

Adipex-P (phentermine): "Hey, guys, I am back with another update. I went on vacation, and even being surrounded by Caribbean food, cupcakes, and off of my usual workout routine, I lost weight! I do suffer from constipation and thirst while on this drug. However, since May 6th I have gone from 291 lbs to 265 lbs. I have lost over 60 pounds in four months, and I'll probably be at over 70 pounds of weight loss by the end of this month! Good luck to you all! Stay encouraged, eat well, and train your body! If you work on developing proper eating habits, the drug will take care of the rest!"

Adipex-P (phentermine): "I started taking this pill because being on depo and an office job has caused me to gain a ton of weight. I will update weekly. Because the first week I have seen a huge change. My energy is back. I don't want to sleep all the time. My focus is back. And I am driven. I have cut out all pop, started watching the calorie intake and I am actually pulling my kids in a wagon every night. We have now extended our walk and I feel great. Starting weight - 6/20/17 - 324 1 week weight - 6/28/17 - 317 (-7 lbs)!!! I could not be happier and I know I am living a healthier lifestyle. With out this med, I don't think I would be able to do it. It suppresses my appetite and boosts my energy. Good luck to all"

Adipex-P (phentermine): "I had a great experience using this lost 20lbs in the 3 months on it. Another positive my face cleared up so so nice!! My skin looked amazing! The first 2 weeks on it I had terrible headaches but they did go away eventually. The only thing I really noticed is that it triggered my anxiety a little bit and caused me to bite my nails a lot!! But other than that I had a wonderful experience with it."

"Update so I started taking this on May 19th, 5ft tall and 250 pounds. I felt dizzy my first three days and ate very little. I try to eat less than 1200 calories a day. Some days I'm still hungry though. It hasn't even been a month and today I weigh 224. That's 26 pounds in 27 days almost a pound a day with no exercise. The results for me have been amazing. I do have trouble sleeping so I usually take the pill earlier in the morning. I take a whole one a day. I also have had severe dry mouth mainly the last 3 days but I'm also taking a water pill."

"Started on Tuesday June 6, 2017. Staring weight was 278lb (126 kg). Today is June 8, 2017. My weight is 269 (122 kg) I also got a B12 shot but it made me sleepy. Has anyone every experienced this? Next Saturday I'm going to try the Lipoden shot. I also went for a two mile walk yesterday and I plan on walking everyday and going to Zumba as well. I started a new job and there's an on site gym. So on lunch I might jump on the treadmill or walk around the building. I'll keep posting updates on my progress.."
