i am 5'4 and have always been a little chunky. My weight was getting out of control, so I went to a weight loss clinc, that my mother in law and sister in law go to, on thursday 02/17/2011 and I weighted 208. That is the most I have ever weighed. I got a lipotropic/b12 shot that day and started the phentermine 37.5 pill the next day. It has only been 5 days since the doctor visit. I haven't weighed myself yet, but I think I have lost some weight. I only drink water now. I don't eat snacks or sugar anymore. I don't excerise at this time, but I plan on starting that soon. I have read a lot of reviews and I hope I am lucky enough to lose a lot of weight.
posted Feb 22nd, 2011 2:53 pmThe first 2 days I only took half a pill (like the doctor told me) and I had a terrible head for those 2 days. I ususally gets headaches anyways, so it didn't bother me. I haven't had a headache since then. It look me a little longer to fall asleep at first, I couldn't turn my brain off and stop thinking for a while, but that has also subsided. My mouth is dry so I am constantly drinking water (which is good). I do not feel hungry at all anymore, I have to force myself to eat. The only other thing I noticed is that I use to remember my dreams every night in very good detail and since I've started these pills, I can't remember any dreams I have.
The doctor office I went to gave me 3 more shots ( to take home and take every week of the lipotropic/b12 ). I have to go back after a month to get another prescribtion for the pills and the shots to take home. I'm hoping I wont have to stay on this too long, but my goal for myself is 130. Thats 78lbs. I'll post when I find out my weight at the month check up.

I started taking Phen on Monday Jan 24, 2011 at the time I was 234lbs ((the largest ive ever been)) and i was shocked when i step on the scale and by Friday Jan 28 I have lost 14LBS!!!! Because of my crazy work schedule I havent had the time to work out or anything but I have changed what i eat, i try to start with a salad and drink 80-100 oz of water everyday, and i stop eatting when i feel full ((no matter how good the food is)) im listening to my body now. I just want to share my story and hope it helps someone. My goal is 160lb and i think i will be there in no time... stay turned for my update :))

+Ive been on phentermine for 3 months and have lost 60lbs. i found out that working out is a plus and a negative. it builds muscle which makes it a little tougher for you to see the weight loss but you keep at it and you will notice it and how much better you look when you start looking at your body instead of loose skin sagging you have a tone figure :) i do think staying off a week or so every now and then is a great idea especially if you notice the weight not coming off as easily.

I started taking phentermine 37.5 on october 15, 2010. I started at 203 lbs. As of today when i left the doctors office, i am 169 lbs. 34 lbs in 3 months!!!!! After the 2nd month i could tell my appetite was coming back. BUT thats when you learn to discipline yourself and continue with diet you've been doing and exercising! Good luck everyone!! DONT GIVE UP!!!

I take 37.5 mg of Phentermine prescribed from the weight loss clinic I go to. I dont work out at all. I watch my carbs (35 per day) and dont drink any sodas or eat any bread. I started in Feb 2010, now I have lost 78 lbs. I know I could have lost more, but went off my diet for a few mos. Back on it now as of last week and already 5 lbs lost. Good luck everyone!!!

+I started taking this on 1-2-11 and its now 1-5-11 i have lost 5lbs so far. I havent had any negative side effects and it really helped reduce my appetite. Cant wait to loose more and be comfortable with myself!

On the Topamax issue. Yes, topamax melts the pounds right off. But after a year.. you have to go off it for a few months and restart. then it melts pounds again. Then.. when you go off if the next time and try to restart it... IT DOES NOT WORK AND i have gained back every pound plus some. The key is to change your lifestyle while you are getting the boost from these meds. If you do not change lifestyle, then it will only be tempory.

Thank you.

I have been taking the generic 15mg capsules for about a month now and I've lost 8.5 lbs. I am very happy with that loss, since I am 50 years old, going through menopause and my metabolism had pretty much come to a screeching halt. However, with the phen, I can keep my food intake to around 1500 calories a day without feeling hungry. I tend to eat 5 small meals instead of 3 big ones. I do supplement with a multi-vitamin to make sure I get all of the nutrients I need, and I pretty much still eat what I like, but I eat it in much smaller portions, as I feel full more quickly. I've sometimes even gone all day without realizing I missed lunch... As far as the side effects, I had some problems the first two weeks with staying asleep, but my body seemed to regulate after a couple of weeks. I also had some minor chest pain for just a couple of days, like when I coughed or took a deep breath it hurt (but no tightness, shorness of breath or shooting pains that might indicate a heart attack) but again, that also regulated after a couple of days. I think it might have been a brief spike in my blood pressure, but it seems to be fine now.
posted Dec 16th, 2010 5:29 pmI have also stepped up my exercise by getting on the treadmill or using the Wii Fit that my husband got me for my birthday this year. The additional exercise has really helped me out on another front as well, because I also have issues with arthritis and the exercise helps to keep me more limber so that I don't have to take the NSAIDs meds as often anymore. Overall, I am very happy with phentermine and will continue to take it as my doctor recommends.

+Trial and error. I've lost weight before on Phen then after a year put it back on which was completely ingnorant. You can build up a tolerance. My doctor recommends taking it for 2 months, go off for two weeks than back on...etc. It works great. So people leaving feedback say they aren't losing on 15MG, I'm a 210lb male and I'm on 30MG and could care less about eating.

I'm about to start taking phentermine tomorrow. I feel that I am also having some trouble with my thyroid and I hope that the combination of this medication and a thyroid medication will stop my sudden weight gain.
posted Dec 15th, 2010 3:27 amI eat really healthy, I work out, I am 5'3" and held pretty steady between 130 and 140 for a couple years. But suddenly, with no change in diet or work out, I gained 15 pounds. I really hope phentermine will help me get back to a more normal size.

+Hi Everyone! My name is Jessica and I have used this med for several years on and off but mostly off. I have learned in this time that diet and walking makes it work wonders. I have been back on it for 16 days and have shedded 10.8 pounds. What keeps me motivate is i weigh EVERYDAY! I use the same scale and wear the same clothes, when you see the scale numbers moving down it puts a smile on your face, and starts your day off great. Some days it may only be a couple of tenths but it still loss. I have stuck to 1500 calories or less, i measure my foods and i don't eat out unless it is healthy. The first 2 weeks were the hardest but it helps. I have taken these pills many times but never lost like this, thats only because i stick to my calories, and to keep up with the calorie intake i have a APP on my phone, (Palm Pixi) Absolute Fitness, yes i paid 4.99 for it, but it helps a great bit. It also keep up with you BMI and Weight! I wish everyone luck, but in order for the weight to come off you will need to put a little effort with the pill. I only walk 20-30 minutes a day, and i have stopped eating fast foods. No sugar or SODAS!!!! I am a southern girl and love my sweet tea but now i use Splenda! GOOD LUCK to all!
