Reviews for Phentermine to treat Weight Loss

"I just started taking this pill today. I ate breakfast and drank 24oz of water before I took this pill. I didn't want to feel sick and have any side effects because I didn't eat first. I didn't not exercise today or eat good, I wanted to see how the pill made me feel before I start eating good and exercising ( which I will do tomorrow). I am early 20s 5"2 SW: 169.4lbs; GW: 130lbs - 120lbs. I have been over weight for 7 years since having my daughter. It's time I get my body back. Throughout the 7 years I lost weight and gained it back. I have good energy levels after taking it. My shoulder hurt some, maybe it's the way I sit. Hopefully it stops. I gave it 5 star cause it Day 1. I will update in about 2 weeks!"

"I started using phentermine for the first time 3 days ago. I have zero appetite and trouble sleeping. Also dry mouth. This pill has given me tons of energy. I lost 120lbs over the past 4 years on my own. Since having two surgeries I put on around 25 to 30lbs. I started out Monday 8/14/17 weighing 166. I will see my Dr in a month. I am 5'4 female and I'm 33 years old my ideal weight by the Dr is between 108 and 145. I have been 166 lbs for a while and it doesn't look that great on me. I felt comfortable at 145 so that my goal. So that's about 20lbs that I need to loose."

"I have been on phentermine for about 6 months and I am now almost 40 pounds down. I have major side effects that I never got before. I have extreme hair loss and I have some bald patches in my head, I just turned 28! My doctor isn't concerned at all and states it's just a side effect and wants to "wean" me off so I don't "withdrawal " after being on it for 6 months. My nails grow cracked now and I have to apply layers and layers of nail polish to keep them from braking and bending. It's awful, I even had to cut my long hair just to avoid my hair falling out so much. I'm scared to take showers, brush my hair and even run my ringers through it since my hair falls out in chunks. Irreversible alopecia is not something I want"

"I started using phentermine when the anti-depressent I've been taking caused uncontrollable weight gain. It's only been two weeks, but I have to say that I am pretty pleased with how this medicine is helping so far. Like everyone says, there is definitely that suppressed appetite, and on a few days I've had to force myself to eat just because I don't have much of a desire. I do have to break the pill in half and take it twice a day because I will have unbelievably surges of energy in the morning and will crash in the afternoon if I don't. I also have noticed changes in my monthly cycle, and the infamous dry mouth. In two weeks I'm down 10 lbs, not too shabby!"

"I started this on 8/11 at 274.4 lbs (female 5'6") and today I am down 4 pounds to 270.4lb. The first day I felt like a tweaker, and had nausea in the morning but I realized it was another medicine I take also making me sick, so today I felt fine. I got a normal lunch portion, and 1/4 of the way through I was done. I haven't thought about food at all. I've made a conscious effort to lower my carb intake to try to get the best results. I had already changed my lifestyle before starting this medicine which I feel will continue to give me better results. It will make you very thirsty so plan on spending a lot of time in the bathroom and refilling your water. I will check back in at the end of the month! Super excited for this little boost!"

"Today I went to see my Dr. Due to the struggle of weight loss. I am 5'10 and started two weeks ago at 215. I started calorie counting to stay under 1750 and cut out soda and sugary beverages. On my own I have lost 7 lbs. My Dr has prescribed me with Adipex P. 37.5 mg tablets 1x a day. I start my journey tomorrow morning with this prescription and was told that I will come back in 1 month and must show at least a 6 lbs loss in order to continue taking it for an additional 2 months before a breaking period. Although I told him I would like to achieve 150 he told me let's start by achieving 170 first. I am excited and nervous but Am motivated. 208 now will update in 30 days!"

"I have been on the pill for 20 days! I started 7/18/17 at 190lb and today, 8/7/17 I weighed 179.8.lb That is a weight loss of 10.2 pounds in a short 20 days. I hurt my leg and was prescribed this medication at that same doctors appointment. I have NOT been able to exercise at ALL due to my injury, so I am hoping that within the next month I am cleared to workout and the weight will fall off even faster! I have no side effects with this medication, other than sometimes having a weird/bad taste in my mouth on days I don't drink as much water. Mainly, I have feeling energized and proud of myself!"

"Started this pill weighing a shocking 300lbs.. Day 11 on phentermine 37.5.. so far lost 10lbs currently weighing 290lbs with no excerise, only a very controlled and strict diet... the first 3 days were horrible side effects wise.. I was drinking 12-16 bottles of water 16oz... My appetite has changed dramatically... just thinking about all the junk food I put in my body for so many years makes me wanna throw up.. AVIOD DRINKING COFFEE I had about 4 coffees on my 4th day and I felt like death was calling my name.. I couldn't breath and my heart felt like it's about to pop out of my chest.. Also I can't sleep normal hours anymore it's 3-5 hours daily.. Otherwise it's an amazing life changing magic pill.."

"Height: 5'2.. Starting weight: 194.. Current weight: 186.. Goal weight : 150.. I have been on the pill on and off for 3 weeks. This pill is a great help when I work morning shifts. I have changed my diet a lot so I'm not sure if its the pill or just the change in diet thats helping with the weight loss. But I'll continue doing what I'm doing and hope the pounds still fall off.This pill definitely gives you energy and makes your throat very dry. It doesn't make me want to drink more water so that's still a struggle lol."

"Took this medication starting in January 2017 5'7" starting weight 184.5 ended medication March weighing in at 144.7 lost at total of 40 pounds!! and was able to maintain it. I have noticed that if I do get off track of my diet I will start to gain. Biggest advise I can give is stay on the diet you followed while taking this pill to maintain your weight. To help fight the cotton mouth besides tons of water I would suck on mints. I counted calories for my diet and didn't go above 1,500 I still continue to do this. I took my pill early in the morning so I could sleep better at night. Good luck everyone :)"

"I have been taking phentermine for about 5 months now. I am on a six month prescription with monthly visits to my doctor to have bp and pulse monitored. I have lost 37 pounds so far in the past 5 months. I do drink only water and I exercise on a treadmill when I have time (not a lot). I do have side effects such as chest tightness, anger when the meds wear off, and my hair has become thinner (I heard the phentermine would do that). Overall I think I have had a good experience with this medication and it has helped me gradually lose weight."

Adipex-P (phentermine): "Hey y'all I'm just checking in again. I've lost sooooo much weight since I've started guys. Omg. I had a baby, my 3rd to be exact and just could never get back to my weight I was before my babies. I'm 5'1 and I weighed 198lbs after my baby. I took the pill April 27 it's not July 30... I've lost 40lbs in 3 months I don't have dry mouth anymore but I still do have a little blurry vision. No high blood pressure and is very healthy. I will stop using this once I reach my goal of 130lbs. Now I do watch what I eat and I calorie count. That could be why I also lost so much so quickly. It's curbs your appetite and you must remember to eat. I love this pill. I'll keep y'all posted :)"

"I started Phentermine 5 days ago and have already lost 6 lbs. I'm 5'6 52 yrs old and hating what menopause is doing to my body. Working out is difficult for me due to needing a knee replacement (thanks to being a competitive runner for 11 years) 5 years ago I weighed 205 lbs and watching what I ate and working out everyday I lost enough weight to get down to 157lb. I have never felt as good as I did then. Since ballooning back up to 195lb I was thrilled when my Dr suggested I start taking Phentermine 30 every morning. As of now I only have energy and focus and motivation. I haven't experienced any mood swings or jitteriness but we shall see.....I do find that I have to force myself to eat tho and when I do it's small portions of Whole Foods."

"I have gained a lot of weight over the past year , I try everything possible to loose the weight. Went to my doctor today and he recommended these tablets for me since I was persistent that he suggest something. I took the first one today and while reading these reviews I feel more confident that this will help me drop some pounds. I am currently 203lbs will give u the update in a month."

"I just started phentermine on 7/21/17. Starting weight at Dr office was 320 and as of today 7/26/17 I am 312. I weigh myself everyday and today I went up a pound from yesterday. I'm really hoping my body is just adjusting to my new diet change. I'll be over the moon once my weight is under 300 again! Just have to work for it!!"

"So I started this pill on 7/18/17 after weighing in at 190lb. I have never been this big, or uncomfortable in my skin, my entire life. I am pretty short around 5'4 and I have to get my BMI down. I have back and hip issues and when I wear too much weight, the pain kills me. In ONE WEEK of being on this medication I have lost 6 pounds, which is huge for me because nothing has helped in months (side-note: I have only been taking a half of a pill per day up until today 8/25/17 when I was a). I am currently sitting at 184.6 and will check in at the end of my first month. My fist goal weight is 165, 2nd goal is 150, third goal weight is 150. Final goal weight is 130-145! As far as side effects, I have not had any but dry mouth! Updates coming!"

"I started this medication two and a half months ago. My regular doctor refused to prescribe anything and my weight continued to climb. I have no excuses. I was completely out of control eating out all the time and eating for no reason other than boredom. I decided to go to a weight loss clinic. I checked in at 217 pounds, 5'7" and 40 year old female. They gave me generic phentermine and I get the Lipo b12 shots weekly. First month down 14 pounds. Second month down 9 pounds. Pretty sure the third month will be higher as I just started my period on the second weigh in and was typically bloated. Dry mouth is the only persistent side effect for me. I drink a lot of water and chew lots of gum. My appetite is nearly non existent and I feel great."

"I started Phentermine 3 weeks ago after the doc advised me that my BMI classified me as "obese." Many people would probably not consider me "obese" in the traditional sense. I am 6'1, male, and three weeks ago I weighed in at 228 pounds. Today, I am down to 207 pounds. I work out with a trainer 3 times a week (but also did this before going on Phentermine, and was hitting a plateau). I am trying to get down to 185 and will probably hit it by September. Question for everyone: My appetite completely disappeared the first three weeks, but it has now slowly started coming back ONLY in the evening (usually around 8 or 9pm). Has anyone else experienced the hunger returning in the evenings at this stage?"
