For Weight Loss (Obesity/Overweight) "I started taking 15 mg, which I believe is the lowest dosage. At first, I felt great. Lots of energy and motivation, and of course, not as hungry. After about a month, I noticed hunger coming back and the energy and motivation went away. My doctor increased the dose to 30 mg, and the medicine kicked in again. It appears that your body can adjust easily to this medicine, which is probably why it is indicated for short-term use only. As far as side effects, I was really worried about it raising my blood pressure and heart rate, but it did not. I had some insomnia at first, as well as some sexual side effects that continue. I have lost about 20 pounds in two months."

For Weight Loss (Obesity/Overweight) "Absolutely amazing! I took Phentermine 2 times a day as my doctor and I wanted to treat my obesity aggressively. I never had anxious feelings or lack of sleep. For the time I was on it, I lost over 70 lbs. I would highly recommend this drug with exercise and eating right."

For Weight Loss (Obesity/Overweight) "I started phentermine on October 10, 2019. The first week, I had dry mouth, insomnia, and jitters. After the first week, all of the side effects seemed to go away as I became more used to it. Today is November 15, 2019, and I have lost 16.4 lbs. I have had enough energy to do 6-7 HIIT classes a week and a low enough appetite to not have cravings. I have also incorporated intermittent fasting as well as cutting all grains, flours, sugars, rice, etc. Only carbs are from vegetables. The first week of the diet change was difficult, but being on the medication makes it easier. Before starting this drug, I’d be lucky if I lost 5 lbs a month with regular diet and exercise."

For Weight Loss (Obesity/Overweight) "I'm 25 years old. I started my weight loss journey on March 27, 2016. My starting weight was at 289, and my height is only 5'5''. I knew I had to make changes in my eating habits and lifestyle. Started taking phentermine on March 27th. I had a hard time sleeping at first and, of course, dry mouth - which just means I need to drink plenty of water. Yes! It does curb my appetite, but the point of the pill is to eat more, but more healthy choices and work out. I just had a weigh-in on August 3rd, and I weighed 254. My goal weight is between 185-220. Next weigh-in, I hope to weigh around 245 or less. I will keep everyone posted."

For Weight Loss (Obesity/Overweight) "I started taking phentermine 37.5 mg on 10/28/2019. It is 10/31/2019, and I've already lost 11 pounds! My eating habits did not change, as I only eat 1 meal a day. I also work out 5 times a week. Toning would show, but I could never drop the weight. This pill has helped tremendously. Side effects are insomnia, dry mouth, excessive sweating, and having to stay close to a bathroom a few hours after taking the pill. However, the side effects seem to be calming down now on my 4th day. Starting weight: 275.5 pounds, weight today: 264.6."

For Weight Loss (Obesity/Overweight) "I am on my 45th day of taking phentermine, and I have lost 33 lbs. I had a little trouble getting to sleep the first few days, but fine now. It does give you a lot of energy, which was one of my problems, and does keep you feeling full. My weight when starting was 292, and I am now down to 259 in only 45 days. I am finally feeling strong enough to do the elliptical for a longer period of time. I started taking the drug to help lose weight because my doctor said I was pre-diabetic, and that was a year ago. So I fooled around for almost a year, going on and off diets and couldn't seem to stick to anything. I never liked the thought of taking pills. But I thought I would give it a try because I didn't want to get diabetes. Happy with it so far."

For Weight Loss (Obesity/Overweight) "I've been taking this medication since 1/18/16. Today marks 6 weeks exactly. On 1/18, I weighed 190. Today, I weigh 161. I need to lose 21-36 lbs to get to my weight goal. I don't exercise as much as I'd like, but I'm on my feet from sunup until sundown and have cut out sodas, snacks, fast food, juices, etc. The side effects are easy to live with when seeing the results. I have dry mouth, my hands shake, I'm easily startled, and I have difficulty sleeping. I have the obvious weight loss, decrease in appetite, and increased energy. I would definitely recommend it!"

For Weight Loss (Obesity/Overweight) "I started taking phentermine 37.5 mg, 1 tab 2 hrs after breakfast and half a tab 6 hrs before sleep. The first day, I experienced a fast heart rate, dry mouth, and insomnia, after a couple of days, it went away. I go to the gym 3 times a week, and I have to remind myself to eat at times. I started on March 30, 2015, weighing 207 lbs, my current weight today, 06/18/15, is 179.6 lbs. I'm really happy, I don't think I have ever weighed this much since junior high. Nothing has worked for me, but phentermine sure has. Highly recommended."

I can't sleep, and I feel lightheaded. I got on the scale this morning, my weight was 175. My goal is 140. I will be updating my progress every week."

For Weight Loss (Obesity/Overweight) "I began taking Phentermine on 12/5/13. At that time, I weighed 181 lbs and had 46% body fat. Today, I weigh 140 lbs and have 33% body fat. I went from a size 14 to a size 6. I still have weight to lose and am continuing to take the medication, but I thought I'd offer my opinion after 5 months on the medicine. It works very well. Having said that, I have had some side effects: dry mouth and insomnia. The dry mouth isn't all bad. It has forced me to drink tons of water, but the insomnia is difficult. I take 1 37.5 mg pill in the morning, but if I've had trouble sleeping for the last few days, I might take 1/2 or skip a dose altogether. Also, the medicine makes me more irritable than normal, but gives me energy to work out."

I feel super energized and able to eat more healthy food since I am not craving food. Only side effect for me is it’s hard to sleep, but going to consult with my doctor today on that."

Phentermine for Weight Loss (Obesity/Overweight) "I started taking Adipex on June 18, 2012. It has worked wonders. The only side effect I have had is terrible dry mouth, but I drink lots of water and chew gum to help with that. I skip one day a week of not taking the medicine, and to date I have lost 20 pounds. That's amazing, 20 pounds in 25 days. I do exercise daily. I walk 3 miles every day. I have lots of energy. When I first started taking the pills, I was not hungry and had to remind myself to eat. I did have a little trouble sleeping. In all, this has been a great experience, and I can't wait until I hit my goal weight."

For Weight Loss (Obesity/Overweight) "I am 54 years old and take 15 mg a day. Because it's like an amphetamine, it gives you amazing energy. From the moment you take a pill in the morning, I pop out of bed like I never have, and even if I have a bad night's sleep, I can work the night with lots of energy. It's like a dream come true. I don't work out whatsoever, and my suits at work are getting too big for me. I've been on it for about 2 months now, and I am at a weight which I haven't been at for many years. I feel muscles in my leg that were always covered by fat, I can now reach around to my back and scratch my back. Any downside to the pill, like sometimes not sleeping well, dry mouth, or even the new fidgeting of my mouth and tongue, which is really weird, is well worth it. I do have problems urinating, I think it has made my prostate enlarged somehow. I also do have dizziness if I bend and pick something up or exert myself doing something, and stand up, you have to be careful."

For Weight Loss (Obesity/Overweight) "I started taking this after going to the Dr and seeing I was not healthy at all. I've never been this big in my 30 yrs of life. I started on October 22nd weighing 226, this morning, I weighed 210. I didn't have a lot of side effects. The first few days, I felt wired and couldn't sleep, but now I just feel full of energy. I cut out all sweets, soda, and energy drinks. I don't crave anything like that except a Sprite here and there, but I'll take 2 drinks and I'm done with it. You do have dry mouth at first, but it just makes you want to drink water, which is good. I absolutely love this and am so thankful for it because my Dr said if I didn't get my health back right, I would have a stroke or heart attack in 5 to 10 years. I recommend this 1000%. Good luck!!"

For Weight Loss (Obesity/Overweight) "I’ve never written a review before, but I will provide facts of my use of phentermine 7.5 mg. I have used phentermine on and off for several years with very little exercising. During my first use, I lost 35 pounds. During my second use, just before Covid, I lost 52 pounds in four months. Phentermine greatly reduced my sugar cravings, especially at nighttime. I don’t know what it is about this drug, but it clearly offers something that my body is not able to produce. I feel normal when I am on phentermine, not running around looking for the next meal or candy, etc. The lone side effect that I have is insomnia the first few nights, but then that goes away. I found taking a half pill the first three nights makes a difference. Though this drug doesn’t work for everybody, my wife has tried it and did not notice a difference, as has my daughter. But for me, it’s my miracle, and for many of you, it will be also. Again, this drug does not work with everybody, so don’t be afraid to try it."

Had so much energy and felt like I could accomplish anything. Weighed myself this morning and down 2 lbs already. Only problem is I only slept an hour. But I’m not tired. Still feel energized. Hope this keeps up. Also took a mile walk with comfort. Feeling great."

Phentermine for Weight Loss (Obesity/Overweight) "I'm 5'5", 240 lbs. After years of exercise and dieting, I just could not seem to lose more than a few pounds. My doctor and I decided I should try Adipex. I just started taking it yesterday (9/15/16). I've noticed a few side effects even just with the first dose. I have a bit of a dry mouth, and it has caused insomnia and a bit of jitteriness too. Granted, it was my first pill, so I'm hoping these will subside after a few days. It has curbed my appetite, and I've noticed an increase in energy. Now I'm not sure if it was due to the medication, but by 5/6:00, I started to feel like I was crashing a little bit. I don't want to give this a rating yet, being as I just started, so I will update at a later time."

For Weight Loss (Obesity/Overweight) "I started my journey on 12/17/15. I made an appointment with a weight loss doctor and started phentermine at 37.5 mg on 12/18/15 at my highest weight ever, 334.8 lbs. So I had my follow-up appointment on 1/13/16, and I weighed in at 320.6!!! That's just by cutting out fast food. In a little over 3 weeks, I lost 14.2 lbs! I'm going to start working out to see how much I will lose before the next appointment. Yes, the side effects are crazy. Dry mouth and lack of sleep are what I experience, but I know my body will adjust with time. You have to choose between staying overweight or taking control of your weight. Just stay strong! It will be worth it when you are truly happy and healthy!! I will keep you posted after my next appointment."

Phentermine for Weight Loss (Obesity/Overweight) "Started taking Adipex-P 4 weeks ago. Cons: constipation and really bad bouts of insomnia - better as time has gone on. Do not take with a blood pressure pill/water pill - you will feel like crap and your heart will try to burst through your ribcage. Pros: lost 31 pounds. 17 pounds - yes, 17 pounds in 1 week, though I do attribute that to the Adipex-P blood pressure/water pill. I found I could not take both at the same time or on the same day, so I stopped taking the blood pressure pill. My blood pressure is down to where it should be. Working out 4-5 times a week. 4-5 miles of cardio per workout plus weights. Probably cut my daily calorie intake by half. I plan on taking the pill for a max of 3 months, so by summer, I should be off the pill but still have a more active life."

For Weight Loss (Obesity/Overweight) "Just started taking this weight loss prescription drug, and it works fabulously! Worst part is dry mouth and feeling like I need to brush my teeth excessively! My appetite is nearly gone, which allows me to choose wisely! I’m drinking safe amounts of water. I lost 10 lbs by the second week! I started at 37.5 mg and have experienced dizziness, taking deep breaths, and increased heart rate with activity, in which I’m monitoring my O2 saturation, which has remained stable at 98% with a resting pulse in the 80s. My BP has always been in the lower range, so no problem there. I’m compulsive about my smile, so I make sure to rinse my mouth out often. I’ve heard these symptoms calm down after a while. I took half a tablet today just to experiment, and my appetite is still little to nothing with fewer side effects. I suggest being mindful, for you know your body and what you can handle. So far, this is working great for me! Worst I could complain about is the dry mouth and insomnia."

For Weight Loss (Obesity/Overweight) "Start date 7/1/19 - 250 lbs, and on 10/31/19 I weighed 190 lb. You HAVE to change your eating habits and be more active. The pill takes away your appetite and cravings. I have to remind myself to eat now. This will be my last month on it because it's only for short-term use. Negative side effects that I've had: very dehydrated, dry mouth, never needing to urinate, a horrible taste in my mouth, feeling like there's a hairball at the back of my throat when I swallow, insomnia. I've only slept between 3-4 hours every night since July. Starting on the 3rd month on the drug, I have a sensation that there are worms burrowing under the skin on my back, under my left shoulder blade. It's a horrible feeling and lasts for a few minutes, several times a day, EVERY. I'm hoping that it goes away after I stop using it. I have had NONE of these side effects prior to taking it, so I know they're caused by the drug. Are the side effects worth it? Yes and no."

For Weight Loss (Obesity/Overweight) "I started taking phentermine 30 mg on 3/18/15. In the first month of using the medication, I dropped 13 lbs (229 lbs to 216 lbs). The initial side effects I experienced included dry mouth, insomnia, and mild headaches. After the first couple of weeks, the only remaining side effect I experienced was dry mouth. This is actually a pretty beneficial side effect as it helps me drink more water. The next month, my doctor bumped me to the 37.5 mg medication. During that month, I lost 12 more pounds (216 lbs to 204 lbs). So overall, I've lost 25 lbs in two months. I'm elated! My first goal is to get to ONEderland (i.e., finally be under 200 lbs). It's nice to actually see some progress. I have hypothyroidism, so weight loss has always been difficult. This helps!"

Phentermine for Weight Loss (Obesity/Overweight) "I started taking Adipex-P in June 2008. I was 193 lbs (F- 5'3'). Today I weigh 158 lbs. At first, I didn't really like the side effects: dry mouth, constipation, couldn't sleep, really bad headaches, so I went back to my doctor about a week after starting the pill. I had lost 10 lbs, I didn't want to stop. The doctor suggested I cut the pills in half and to try to eat and drink more often. It turned out that it worked for me. I would take a 30-day supply, cut the pills in half, and I don't do weekends. After that 30-day supply was done, I get off the pill for a month to make sure I don't just regain the weight. Oh, and I don't exercise or eat healthy, I just watch how much I'm eating. Also, no soda."

For Weight Loss (Obesity/Overweight) "Spent the last year eating very healthy and exercising with very little weight loss results. I got desperate last week and went to a weight loss clinic and got on phentermine and B12 injections. Weighed in last Tuesday at 169.7 lbs and went in for my one-week check-up and weighed 165.3 with jeans on, and last time I was wearing shorts, so I've lost about 4.5 pounds in one week. You have to push through the first three days of jitteriness and insomnia, and then it levels out and you feel normal. I have experienced some pretty gnarly dry mouth despite how much water I drink, but it's worth it if these results keep up. I'll update again in a couple of weeks!"
