For Weight Loss (Obesity/Overweight) "5'11 and I weigh 170, yes I'm tall but this is the heaviest I've been and I'm not happy with it. Side effects: no sleep, lower back aches, dry mouth, made me angry which I'm never angry. Also here and there a little depressed. But I would have to snap out of it very quickly. But overall it's a good pill to take if you have self-control and you won't get addicted to it. It gives you lots of energy which I like to work out in the gym or go for a jog at a park. You will lose weight quickly but you have to maintain it. I have a sweet tooth so I would eat chocolate after I lost all my weight then I would see I gained weight like 2 lbs and I would work out the next day. You have to be consistent and dedicated."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I am 5'5' and 31 years old. I have been overweight my whole life, even as a child. At my heaviest, I weighed 256 lbs. I could hardly make it up and down the stairs. That is when I started taking Adipex. I am now 149 lbs and feel amazing! I know that there are side effects with every medicine, but there are also side effects to being overweight. Honestly, it is not easy to wean off. You have to work hard every day, not to cave into the cravings, and keep active. It gave me the edge I needed to make that life change. Other friends have tried using Adipex but could not stick to the diet and exercise plan and lost little to no weight! You need to want to make the change, the pills just help."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I've taken Adipex on and off for about 14 years now. Each time it definitely works. It's the only thing that has ever worked for me. I always gain back what I've lost when I stop taking it though, but I've also had 2 back surgeries within the last 8 years that contributed. This time I'm really focusing on changing my eating habits and doing the Paleo diet with the Adipex. So far, I've lost 84 lbs. in a year!! I walk/exercise but have to take breaks when my back acts up. It's more than calorie reduction. You have to eat the right stuff along with the calorie reduction or you'll have cravings and it'll be harder to keep off once you come off it. Stay committed to drinking lots of water. That's a main key. Bottom line, it works but you've got to work with it. You've got to do your part and take it seriously. I've gone from a miserable 256 lbs. to 172 lbs. and I'm aiming for 150 lbs. I was 135 lbs. before I had kids, 20 years ago, so I'm getting close! There is hope! Patience, determination, and commitment."

Drinking 65 to 70 ounces of water a day along with a 1,800 calorie diet. No sugar, no soda, no fast food. Everything fresh and baked, not fried. More updates next month."

For Weight Loss (Obesity/Overweight) "I started my pills Phentermine 37.5 mg on Feb 18, 2015. At 337.2 lbs on that day. As of today, Feb 24, 2015, I am 319.4 lbs, 17.8 lbs lost. The only side effect is dry mouth, so I'm drinking plenty of water. I also take Xenical 120 mg, one capsule half an hour after my last meal of the day, at 8:30 pm. My weight goal is to get down to 250 lbs, and once I hit that goal, I will set my goal to 225 lbs, going one step at a time. I'm proud of all of you, keep up the good work."

For Weight Loss (Obesity/Overweight) "Please, for those of you who read reviews, don’t make such high expectations of yourself. I’m seeing that you weigh 200+ pounds and your goals are around or under the 150 mark, which is completely understandable to want to reach. In my past, I have set such high expectations and failed miserably, which made me feel even worse. I have learned that it’s so much more satisfying to reach tinier, more realistic goals in a shorter time span. Tell yourself that your first goal is 10 pounds. You’ll work hard, and when it happens, you’ll be motivated for more. Set another realistic goal. Reward yourself. Not with food, but just a little something to say 'job well done.' It works. Me - 310 to 185."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "At 280 pounds, recently diagnosed with Type 2 Diabetes, and told to start medications, I turned to my doctor to discuss potential stomach procedures. Well, with 1 kidney, I'm pretty certain Diabetes would eventually cut my life short so why not go through a drastic change? No, instead I asked her for three months to lose 30 pounds, and she suggested I try Adipex/Phentermine 37.5mg. So like many of you, I did, and I instantly felt that sudden feel-good surge of energy. I'm now 10 weeks in and lost 33.5 pounds. Some will read this and many of your posts and instantly think it's a fake review. But honestly, readers, this pill has changed my outlook on life. Give it a shot, it may not work for all, but it may work for you!"

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "Started the Adipex-P June 4th and it is now July 31st and I’ve lost 35 pounds. I’m now at 180 lb. No complaints about this medication but I wouldn’t advise taking caffeine while on it or you won’t be able to sleep for days. Lost 17 pounds the first month. Helps me feel motivated and I’m able to fall asleep just fine. The first week I wasn’t able to get much sleep but my body soon became used to the medication."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I've been on this medicine off and on for 6 months. I've lost about 30 pounds. My cycle is 1 month on and one month off. If you take it more than a month, your body gets used to it. I have found giving the body a rest and allowing the metabolism to adjust without works best for long-term weight loss and maintaining. I started at 180, currently at 150. I get bad side effects, but seeing the scale move and clothes fit motivates me to move on. If you exercise with this medicine, it can make you nauseated and cause vomiting. Exercising first thing in the morning, then taking the medicine, works best to prevent nausea and vomiting. Also, I find it important for users to change eating habits. Suggest clean eating 6 days on, 1 day off."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I have been taking Adipex for about 5-6 years. All I can say is that some of you will feel bad or very bad after taking it but most importantly, it is to take vitamins and minerals along with Adipex. I had back pain, heart racing, and then even felt like my heart stopped for 2 seconds. It was scary but I started to listen to my body. I drank lots of water, ate loads of spinach and leafy greens, and took vitamins constantly. It is also strongly advisable not to eat any meat or heavy meals. Please remember that despite the fact that you get loads of energy, your bowels are sleeping, you can hardly feel any movement in your stomach. Phentermine is blocking the 'hunger center' in your brain. I hope it helps. I have reduced all the side effects I've had."

Lomaira (phentermine) for Weight Loss (Obesity/Overweight) "I heard about this from my doctor because I had asked about Ozempic and Wegovy to see if I was a candidate. She mentioned that those drugs are typically used for diabetes, but they saw that patients were also losing weight and started using it off-label. She recommended I try a drug called Lomaira that's a low dose and isn't as complicated as a diabetes injection. I didn't realize those products were injections. She also mentioned the side effects can be bad, and each injection lasts for a whole week. I can't imagine having stomach problems for an entire week without being able to stop. I've been on Lomaira for 8 weeks and lost 30 lbs. I've lost about 25% of my excess body weight. The side effects were mild to non-existent. I was thirsty for the first week, but I did not have any other issues. I take Lomaira 2x a day before breakfast and lunch. I have not had any sleep issues. If I feel like eating on the weekends, I skip a dose, and everything is fine. Good luck."

I hope this kind of weight loss continues, but I'll have to wait and see. I did experience a little bit of nausea for the first few days, but it wasn't too bad, and dry mouth a little. So far I am pretty pleased."

For Weight Loss (Obesity/Overweight) "I went to a weight loss clinic on January 4, 2021. The doctor put me on an old-fashioned low-fat diet and phentermine. Wow! I went from 218 lbs on January 4 to 210 lbs this morning. The dry mouth is lessening. No more jitters or anxiety. I really don't think about food. The doctor told me not to spend too much time in the gym because I am not training for athletics, and most people get into routines they will not sustain. He told me to walk a bit every day and to continue my yoga daily, even if for just 15 minutes. I take trazodone for sleeplessness. It's not a sleeping pill but an antidepressant. It doesn't have the harmful side effects of regular sleeping pills. When combined with melatonin, it really helps. I don't take phentermine every day. I think it accumulates in my system and keeps me awake unless I mix it up a bit. Some days I take half a dose, and today I took none. I believe I will sleep better tonight and still get the benefits of a reduced appetite."

For Weight Loss (Obesity/Overweight) "My body demographics: age 28, 5’1”, Starting weight as of 2/18 was 180lbs. I breastfed my child til 10mo then instantly gained 30lbs after I stopped (warning to all breastfeeding moms!). I would exercise, went on every extreme diet you could think of for weeks and sometimes months at a time, and usually could only manage to shake about 2lbs. After just three doses of this medicine, I’m already down 6lbs. Yes, there are side effects, but it’s worth it to me. I definitely have the dry mouth and headaches, but it makes me drink more water. I was incredibly addicted to Mt. Dew. Since I’ve started, all I want is water. I hardly have an appetite. I eat less than half of what I had been. It’s a miracle in pill form!"

For Weight Loss (Obesity/Overweight) "This pill is AMAZING. I have recommended it to all my friends. My stress hunger and ALL my cravings went away. I am notorious for eating sweets and that’s one of my weaknesses. One of the best things that I enjoy about this medicine is the ability to take your hunger away. Some things to note are that while on this medication, it says do not consume alcohol. With that being said, I do like to have an occasional drink. When I knew I was going to have a cheat day, I didn’t take the pill that day because it negates the purpose of this pill. Also, I drank coffee one morning before an exam and took the pill at the same time, and it was a bad idea. It overstimulated me. For those that are considering this medication and want to be a healthier, happier, skinnier you, I highly recommend it. Make the choices to eat right while your appetite is suppressed. Weight loss is one of the hardest journeys to undertake! Good luck to all of y’all!!!"

For Weight Loss (Obesity/Overweight) "Taking this medication for 4 months now, I was 203 pounds in March and down to 169 pounds now (July), feeling good. I'm 33 years old, I've always struggled with my weight and binge eating disorder, but it got worse during the pandemic. I was binge eating every day, and I couldn't control it - I was 203 pounds, the heaviest I've ever gotten. I was uncomfortable in my own skin, so I decided to look for help because I couldn't do it on my own, even though I tried. The doctor prescribed phentermine. It took away most of my appetite and cravings - I felt hungry, but I would eat just the necessary. I still have binge eating episodes when I have PMS, but not as bad as before. Not many side effects for me, just a VERY dry mouth, it made me drink more water, which is good. I experienced insomnia sometimes, and a little headache and constipation in the first week. I recommend it to people who want to get healthier but can't do it alone, just don't forget that you have to be strong to keep the results. It's not a miracle pill."

For Weight Loss (Obesity/Overweight) "SW 283, GW 167, CW 223! Lost 60 lbs in a little more than 4 months. Take phentermine about 5 days per week. Use MyFitnessPal. Walk and hike a lot. Weight train a little. Try to eat as much protein as I can and be carb conscious. So glad I don’t have significant negative side effects. They were worse during the first week, but now I am just thirsty and have mild to moderate constipation. I’d say it’s worth it. And if you can, push through the first week of sweaty palms, etc., unless of course it causes significant medical concerns. Also, I have adopted a bit of a zig-zag pattern to calorie consumption with one very low-calorie day per week. This is working for me. Glad to be more than halfway to my goal!"

I run 5 miles every day and have totally changed my lifestyle. Drinking lots of water, I probably go through a case and a half a week. I did experience dry mouth and a serious boost of energy the first day I took it. After that, it's just been dry mouth but hey, I'm accustomed to drinking a ton of water. If you change your lifestyle and hit the gym, it works."
