For Weight Loss (Obesity/Overweight) "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 10 a.m. At least two hours later, I started to feel weird, not a bad weird either. I just felt alert, awake, and so energized 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 some way 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!"

Phentermine for Weight Loss (Obesity/Overweight) "I'm 39 years old, height is 5'4'', and I have been on Adipex for a month now, and this medicine works. Before, I weighed 199 lbs, and now I'm down to 181 lbs. I haven't started going to the gym yet. I just watch what I eat. I take half of the tablet every day around 10:30 a.m. Yes, I experience dry mouth, but that helps in drinking lots of water. I had jitters the first week, and that is gone now. It didn't bother me at all because I have a set goal. I just joined the gym and will be starting next week. I will update you after a week in the gym... Good luck to all."

For Weight Loss (Obesity/Overweight) "I started phentermine on 3/1/14, my starting weight was 205 lbs. I have been steadily going up due to medical issues. At first, the side effects were foggy brain and the jitters. Shortly after the first week, I had to have my gallbladder out, so I had to stop. I started the medicine again, and with being on the medicine for a total of two weeks, I am now down to 193 lbs, that is a loss of 12 pounds in just two weeks. Very excited and happy with it so far."

For Weight Loss (Obesity/Overweight) "I started taking phentermine 37.5 mg on October 18, 2017, once a day. I initially weighed in at 211 lb on the date I started taking the medication. As of today, November 18, 2017, I have lost 20 lbs. I am down to 190 lbs!!! I have completely changed my eating habits to no red meats, fried foods, starches, and I try to keep my calorie count right at 1425 per day, which was difficult at first, but now it's much easier. I don't drink soda or coffee anymore, but I'm super thirsty all the time. The first weekend I took the medication, it made me very jittery, and I suffered from insomnia and horrible headaches. After the first four days of being on the medication, my symptoms improved and eventually went away. I would recommend starting this medication on a weekend."

For Weight Loss (Obesity/Overweight) "My doctor prescribed me phentermine 37.5 mg. I've recently just started the medicine yesterday, on 10/25/2017, and so far I have jitters, a little dry mouth, I'm full of energy, and I have no appetite! The good thing is I feel like I can run a marathon. I drink plenty of water a day and portion my food intake. I plan on eating healthier and working out daily. My starting weight is 265 lb. I plan on going back to my college weight, which was 188 lb. I'm excited for this journey and to keep you guys updated."

Phentermine "I've been taking Adipex 37.5 mg for 4 weeks and have lost 20 lbs. I take half a pill in the morning, the other half early afternoon. No jitters, shakes, or bad side effects this way. LOVE the results, so happy!"

Phentermine for Weight Loss (Obesity/Overweight) "I have been on Adipex for one week, to lose the last 30 lbs. (I have lost 80 on my own-but plateaued forever!). In the past week, I have lost 10 lbs. I am so excited to be closer to my goal. I never feel my heart racing or shaky, and I am one of the rare people that it helps relax. I have adult ADD. The first few days on the medicine, I took a nap-that never happens."

Phentermine for Weight Loss (Obesity/Overweight) "I started phentermine (Adipex-P) 37.5 MG tablets on 01-14-2022. My current weight is 235 lbs. It took about 30 to 45 minutes to feel the energy that it gives you, but I didn’t get the jitters or anything. I was on 15 MG capsules, but it didn’t work well for me. I can tell you more after time passes. My goal is to lose 50 lbs (185 lbs). I am on a good diet, a lifestyle change for the better, so this weight will stay off for good!!"

For Weight Loss (Obesity/Overweight) "I've been taking phentermine 15 mg twice a day for about a week now and have lost about 7 lbs so far. I do feel the dry mouth, a bit of the jitters, feel like I don't have a full night's rest. The oddest sensation has been anxiety while driving. I didn't see anyone report such a feeling, but I've never had any issues behind the wheel ever before. I would like to continue on my goal and will give it another week or so. If anyone has had this occur to them before, please share. Good luck to everyone."

For Weight Loss (Obesity/Overweight) "Today is day 5 of being on the medicine. I have PCOS (Polycystic Ovarian Syndrome), and as a result, I am overweight, and it is very difficult to lose due to excess testosterone in my body. That being said, I am 5'2" and was 230 lbs in April 2015. I went vegan for 4 months, and I lost about 18 lbs with intense exercise 3 times a week. As of June 5th, I was 212 and then down to 202 in October. I was put on Metformin in October to help with weight loss, but since then, I am only down to 197. The doctor decided to take me off that and try this. I am very used to stimulants and caffeine, so the jitters don't really affect me. No other side effects as of yet. I will update further along with a new weight. So far, I am happy with the switch."

For Weight Loss (Obesity/Overweight) "I'm 5'3", 184 lbs (starting weight). I started taking this on Jan 29. Small pill, easy to swallow. No nasty aftertaste. I take my pill when I wake, which is 6:30 am, only because I've read reviews where they could not sleep, and I didn't want the problem. 15-30 mins after ingesting the pill, I also experience the jitters. Which can be easily taken care of by just eating breakfast. You're full of energy all day. The 1st day, it did not suppress my appetite like I thought it would, so I went on eating as normal. Day 2, I took the pill at 6:30 am, shortly after I get the jitters. I eat my breakfast, and the jitters go away. Day 2: jitters (just eat), dry mouth (drink water), energy, no appetite, and insomnia. I only got 2 1/2 hrs but felt great in the morning!"

Phentermine for Weight Loss (Obesity/Overweight) "Consumers, I've been on Fastin off and on for about a year now. I read most of the comments before posting my experience. I usually only take 1 in the morning before I worked out to give me the energy I need to complete my 5-mile walk. If I'm not working out that day, I take half of a pill due to the fast heart rate and slightly the jitters. To be honest, I haven't seen much of a weight loss. Could be I'll start for a week or 2 and then stop. My issue is I need to be consistent with working out and taking the pill to see results. I do believe they would work if taken properly. I read one comment, and the consumer said she lost 35 lbs, so that there is inspiring me to push forward to achieve my weight loss goal."

Phentermine for Weight Loss (Obesity/Overweight) "I have only been on Adipex for a week and a half now, and lost about 4 pounds in the first 3 days, but now I am at a standstill again. I am on a 37.5 dose and have never experienced jitters, extra energy, and worst of all, I am still hungry! I do not eat that much in hopes I will still lose weight. Also, I work out at home for at least an hour, 3-5 times a week, mixing cardio with weights. I only have the prescription for one month, so we will see how the other 2 1/2 weeks go."

I have experienced loss of appetite, dry mouth, headaches, nausea, jitters, loss of memory, and have a bad taste in my mouth. I'm pleased with the weight loss, but the side effects are bothersome, so after I am done with this month's supply, I'll stop. Starting weight 181 lbs."

For Weight Loss (Obesity/Overweight) "Started the drug 1/3/2018 and didn't make it the full month! I guess I won the lottery when it came to the side effects. Started with dry mouth, but I had energy, and the pill was working, so I thought I could deal with it. Around week 3, the fun started. Here we go: ringing in my ears/sensitivity to sound, hand tremors, numbness from my elbows to my hands, which made movement difficult, euphoria, dizziness, ABSOLUTE CONFUSION. I had trouble focusing when speaking to people and trouble forming sentences, flushed face, and intense jaw clenching. I am really bummed because I did lose 8 lbs in the month I was on it. Darn...."

For Weight Loss (Obesity/Overweight) "I started out at 208 lbs and have been doing a limbo for the past year, never going past 203 lbs in weight loss. This is with crazy workouts at the gym, an all-liquid diet until I get sick, the works. So my doctor prescribed Adipex for me. Well, the first day I took it, and a few hours later, being Saturday, I wanted to take a nap. So I lay down for 20 minutes and then got a huge spell of energy. That night, no sleep whatsoever. In fact, I got up at 6:30 am out of boredom and rearranged the living room furniture. Side effects were cotton mouth, a few jitters, and weird dreams. Got to sleep after the second night, but have dropped 8 pounds so far. I hope it keeps going. My goal is 150 lbs."

For Weight Loss (Obesity/Overweight) "About 3 years ago, I was 70 lbs overweight. I decided, what the heck, let me try phentermine. I only took 1/2 pill per day. The first week I felt the side effects like a little shaky, etc. I just kept taking 1/2 pill per day. I did not change my eating habits, the drug did that for me. The weight started just falling off. I lost 50 lbs in 3 months and eventually got down to my goal of 70 lbs. I haven't taken it in 2 years and have slowly crept back up, about 20 lbs, and still have about 30 pills left."

For Weight Loss (Obesity/Overweight) "I've been taking phentermine 37.5 for a while now. Since June 7, it is now July 20, and I have only lost 8 pounds. I don't have an appetite at all, I have to force myself to eat. I think it's only like 1000 calories a day, if that. I have really bad heartburn and have some insomnia. Other than that, I haven't experienced anything else. I am 5'6" and started off weighing 180, I'm down to 172. I did have an episode of jitters, tingly arms, rapid heartbeat, and cold sweats, but I ate an apple and felt much better. I'm not sure if the pill is actually helping me lose weight since I've been on it for 44 days and have only lost 8 pounds."

Today is 10/16/16, and I feel more hungry than day 1. I ate a total of 1,400 calories today. I did have a lot of energy....I actually washed baseboards and all. I hope it continues to curb my appetite. So far, no bad reports."

For Weight Loss (Obesity/Overweight) "I was on Phentermine. I lost 8 pounds because I also take Effexor, Topamax, and Clonidine for other symptoms. My insurance company considered this a trial. I, after three months, was no longer covered for the drug because I couldn't lose ten pounds because of my other conditions. I now am going through horrific withdrawals. I cannot sleep nor eat properly. I have to constantly drink something to produce saliva. I shake constantly and have nightmares from this medication. If you are on this medication, DO NOT STOP TAKING IT!!! I learned the extremely hard way that this medication IS addictive! My doctor told me the psychiatric effects are my mental illness NOT the medication! So, I advise anyone, do not take this with psychiatric meds!"

For Weight Loss (Obesity/Overweight) "I have hypothyroidism and in March had a complete hysterectomy and BSO with other complications. Was off work 8 weeks and I've gained 30 lbs since. I'm 5'9 and now 164 lbs (used to be 135). Today, my first pill. I was prepared for side effects and am having jitters, skin tingling, dry mouth, and slightly elevated pulse. The doctor put me on this because estrogen patches can make thyroid meds less effective, plus my gynecologist had me on too high a dose of testosterone (part of HRT), so double weight gain whammy. I'll post on this every few days, crossing my fingers!"

For Weight Loss (Obesity/Overweight) "I have been on Adipex for two days now. Already I can feel the difference. Food is no longer an obsession, and I want to do other things. I've not so far had any side effects except for the super dry mouth that everyone describes, it just adds to my water intake, so I am fine with that. I do not want to eat. I have to actually be hungry to eat. I lost 3.4 lbs in two days' time. I can't wait to see what happens with this pill. I weigh 255, and that is too much, I wasn't even that big when I was pregnant. A weird thing, too, when I actually do get hungry, I crave healthy veggies and fruits and such! I do feel a bit of a 'rush' about an hour after taking it, it goes away after a bit. The first day I was a bit shaky, but I didn't experience that since."

For Weight Loss (Obesity/Overweight) "I started taking phentermine 30 mg on Feb 9th, 2011. My starting weight was 232 lbs. I just had my first child 6 months ago, and I haven't been able to lose any weight since then. I finally decided, after speaking with a friend that lost weight using phentermine, I would give it a try. Today, Feb 17th, 2011, I weighed myself this morning and I am 219. That's 13 lbs in 9 days. I can't believe it. I love this pill, it's the only thing that has helped me so far. I have no appetite, and when I do, I eat very small portions. I have minor side effects like dry mouth, light headache, and jitters right after taking it. Jitters usually go away after about an hour, but I still have tons of energy throughout the day. My goal weight is 165 - 170 lbs by June 12th, 2011."

My doctor also gave me Wellbutrin to help with jitters. Most days I don’t have a lot of energy. I work out 3-4 days per week, this includes strength training and cardio. I’ve taken Adipex in the past, and the most weight I’ve ever lost was 10 lbs., which took 2 months to lose. I’m thinking about starting to take a whole pill."
