For Obesity: "Dec 23, my doctor had me start this. My first week I experienced all the symptoms and lost 5 lbs in three days (I had to force myself to eat and I couldn't sleep). I seem to have adjusted now but have gained the weight back. I'm confused since I work out hard 5 to 6 days a week. I eat less than 2000 calories a day. I feel like I would starve at 1200 like I see most of you post. Should I be restricting to 1200? My doctor didn't mention this to me. On a positive note, I do feel more energized when I work out. I feel like I don't want to stop exercising. My doctor prescribed this for me to give my metabolism a boost, I've lost 70lbs w/o the pill but haven't lost anything for 6 months, been at the weight. Maybe I need to have it a month...."

Fastin (phentermine) for Weight Loss: "Fastin, there's nothing like it. Amazing. You lose a pound a day if you eat breakfast then take one. Then lunch and another one. And drink a gallon of water a day. There's something with drinking that much water that allows you to drop a pound a day. You are going to pee every hour until the fifth day when your body get use to a gallon a day water...try it. When her heart races, take slow gentle breaths until you feel your heart slows."

For Weight Loss: "Okay so I'm starting my journey on phentermine 37.5 today. I am a female weighing 233, height is 5 feet 1. So far the only side effect I notice is diarrhea. I have read the previous stories. I hope this works out for me. I will give an update later - also I noticed I can't eat as much."

For Weight Loss: "I started taking phentermine on August 2015 weighing 167 at 5'3". One month after I was down to 154. Took 4 months off and was able to to maintain 155-157 weight and now I am back for another round. No hunger just thirsty and dry mouth. A little bit of energy as well. I noticed though that I felt a little blah while I was off it."

Adipex-P (phentermine) for Weight Loss: "This product is the real deal. I lost 20 pounds in 1 month. The first week I felt weird, like I was high. The energy is great.I never exercised because I was over whelmed with my job & school. And I ate what I wanted to. I only drink lots of water and sometimes with Crystal Light, no sweets. Everyone wants to know what I am doing. I recommend this to everyone that needs a boost to drop the pounds. I started 188, today I'm 162. That's a lost of 26 pounds in 5 weeks. Next week I will start exercising."

For Weight Loss: "I have Hashimoto's and have been just been gaining weight for last 8 years. Started at 197# 5'8" 50 yo. Tried Qysemia a year or 2 ago with no results at all (very disappointing). Starting "Eating Clean" and dropped a few pounds the first week but gained them right back. Work out with a trainer 3xWk for last 6 months - nothing (but stronger). Just Started 15 mg phentermine and down 5 lbs first week. I feel no boost of energy nor do I think I am eating less but still down. Hope it continues!"

For Weight Loss: "I was put on Phetermine to aid in my weight loss, I had tried everything, even used Herbalife strictly for one month and didn't lose any weight, I was concerned about hypothyroidism as thyroid problems run in my family, but at 26 it shouldn't be posing an issue and blood work came back normal, I chalked it up to a metabolic problem and consulted with my doctor. On the day of my visit my resting blood pressure was 149/93, I don't get nervous at the doctor because I'm a veterinary technician so I see needles and help treat animals all day so those things don't bother me. I am 5'2 and my weight at the doctor was 192lbs. My doctor wants me back in 1m to see how I'm doing, she requested I lose 5lbs by the time she sees me. So far I've lost 9lbs."

I was elated I couldn't believe how fast I was losing weight, but now I'm stuck I haven't lost anymore weight sometimes I even go up a pound or two. I've hit a wall and it's almost like I'm wasting the pills now and I don't know what to do I'm feeling very discouraged. Help?"

So I went from 145 to 190 in a year! The weight just keeps adding on which is making my blood pressure sky rocket. I have never been this heavy. Can anyone please give me advice!?

For Weight Loss: "Hey everyone....I posted around day 5 of taking....it is down below (which gives you my background with PCOS & my journey). I started Phentermine 37.5 at 197lbs on Dec. 3rd. I did weigh myself on day 12 and I was down to 189 lbs. I think that pretty much says it all. I am not really experiencing the main side effects (dry mouth, jitters, insomnia). I can drink coffee, and I do my best to keep to 1,200 calories a day. I do not exercise. I sit at a desk all day, then nanny for 4 hours in the afternoon. The only side effect that is a little annoying, is constipation. This is troublesome because I normally have stomach trouble. I am trying Prune Juice as of today."

For Weight Loss: "I was prescribed phentermine almost two years ago for a three month period. This drug is wonderful! I lost 50 pounds and managed to keep it off! You must use your time while on phentermine to learn how to eat correctly or you will gain the weight back. Be realistic about your portion sizes and give up processed foods. Not only did I lose the weight while on phentermine I continued to lose weight ( 15lb) after I stopped taking the medication due to my new healthy lifestyle. My BMI is normal now!!!"

For Weight Loss: "*Update* I'm 5'9, 29 yr, female, started at 266lbs. It's day 36, and I've lost about 16 pounds. The only thing I experienced was dry mouth within the first week. Since then that has subsided, but now my feet and hands are tingly. It's not severe but enough to be annoying. I still feel great. No other side effects. Since taking it, I'm teaching myself to choose better foods and make smaller plates. Trying to establish good habits while it's easy to do so. I haven't incorporated exercise in my routine yet, but I can't wait to see results when I do! Still moving forward with it."

For Weight Loss: "I started phentermine on 10/28 at 318 lbs. I was miserably depressed and my weight had spiraled out of control after getting married and having a baby. I had tried to lose and I found it nearly impossible. With phentermine, I have energy and my appetite is very controlled. I limit my carb intake and eat 1400 calories per day. I work out 3-5 times per week and my endurance has greatly improved and there is a huge difference in the way I feel. I have lost 33 lbs in 7 weeks. I expect to lose 10 lbs per month and I am very satisfied with that. No side effects to speak of. I am very happy my doctor prescribed this for me!"

Adipex-P (phentermine) for Obesity: "I've only been taking this med for 5 days, but I don't get any of the extra energy that my doctor said I would. Does it take a while to get in your system or is it supposed to work immediately?"

Fastin (phentermine) for Weight Loss: "I was prescribed Fastin for weightloss . The prescription pills worked great not a single bad side effect I lost over 50 lbs in about 4 months. It gave me energy to start working out and WOW did my concentration for work improve . However the pills were costly and given out in office only. So every month it was 40 for the Dr visit and weigh in and another 40 for 1 months worth of pills . When I was unable to afford this regimen I looked for cheaper alternatives. I got some over the counter bottle of FASTIN I bought 2 bottles. These are unhealthy, way over caffinated Crap! I had gotton very ill half way in to taking the first bottle and had to stop bcaz jitters, headache, paranoia racing heart !!! My advise pay for the real stuff."

For Weight Loss: "I was on Phentermine for about a week and I was losing weight but the side effects were insane. Throughout those 7 days I had severe throbbing pain on the left side of my head. The pain would start from the top and run down. What made me stop taking this pill was when the left side of my face started to get a little numb. That scared me and I immediately stopt taking Phentermine. The next day the severe throbbing pain was gone. Now it's been about 2 months since I've stopped taking Phentermine and the headaches have begun. So yesterday I went to my doctor and I explained to her that the only time I've had throbbing pain was when I took these pills. She then told me that I was experiencing migraines. I've had headaches before but pain like"

Adipex-P (phentermine) for Weight Loss: "I am female, I am 5'6 and weight 170lbs, I have never been this heavy, not even pregnant . The most I have weighted is around 150. My goal is to get back to that size. Today is my first day taking apidex. I will check back in, in 2 weeks with updates."

Adipex-P (phentermine) for Weight Loss: "I started taking this pill Jan. 16, 2012. I was a 235lb, 5'4 female. In one week I lost 13lbs. I lost a total of 90 lbs in 4 and a half months and have kept it off almost 4yrs. BUT:::::: This pill will only be successful if you make life changes. It will increase energy and curb appetite while you take it. You will lose weight quickly. As soon as you stop, however, you will crave all the nutrients you have deprived your body of while trying to follow a 1000/1200 calorie a day diet.....thus gaining the weight back just as quickly if not careful to stick with portion control"

For Weight Loss: "I joined a weightloss clinic because I have been struggling to loose 30 pounds for about 7 years. I loose 6-10, then gain it back, then repeat. I went last Thursday and got a B6/B-12 shot and the pills. I weighed 168. I'm trying to get to around 135. When I returned yesterday, a week later I weighed 162...down 6 pounds. I take the pill between 7 and 8am and it really curbs my appetite and cravings. I don't even feel like eating. Sometimes I only eat because my stomach is growling or I start to feel a little light headed. It really does curb your appetite. I am working on eating clean and exercising, so I am making a lifestyle change that will last once I finish taking the pills. Wish me luck!"

For Weight Loss: "I have PCOS and have struggled with weight loss my whole life. I've been on Phentermine for about 3 and a half months now. I started at 265 and am now at 229. So I've lost 36 pounds. I diet with this medication because I won't let myself gain it back when my times up. I eat around 1600 calories a day And only drink water or teas with honey. This medication has changed my life and I love it. I do have dry mouth. And the energy messes with my sleep most nights. But it's great and I recommend it to people often"

Adipex-P (phentermine) for Weight Loss: "I am 5ft & 160#. Um a short round pear. I started Adipex in September (I think) I have only lost 10lbs. I put on a lot of weight when I started taking my thyroid medicine. I have changed up my eating habits some & have been trying to go to the gym 3 days a week. & go walking with my dog on the weekends. At first when I took it I had light headaches & I felt like I lost all my energy by mid afternoon & was a little constipated. Now I feel fine. Dry mouth & still light constipation. I just thought it would work a little better for me. I am trying to eat better it can be so hard when I have to make dinner for hubby & make me something else & being around the holidays. I am hoping to loose 20 more pounds."

Adipex-P (phentermine) for Weight Loss: "I took this medication two years ago, I was on it for six months, I didn't drop weight but I did loose inches. I was wearing a size 26 in plus size and went down to a 22. I just started taking this again two days ago, my current weight is 295, I am 5'5, female, and currently wearing a size 22 plus size. I am drinking premier protien shakes once a day for extra protien and meal replacement since I work over nights. I eat breakfast, have my shake for lunch, and eat a small amount for dinner but keeping my calorie intake between 900-1200 calories a day, I have replaced sweet tea with flavored bottled water, and I'm counting my steps for exercise. I am hoping to get down to a size 18 within 3 months. Wish me luck."

For Weight Loss: "Male, age 49. I've climbed the ladder to a nice cushy office job with little or no walking. Regular days are 12-16 hours, leave when it's dark come home when it's dark. A co- worker introduced me to his doctor for a wellness visit, he prescribed phentrimine 30 mg and I've lost 14lbs in 30 days. I honestly have very little time away from work and this loss in weight was simply smaller portions, lots of water and having enough self control to eliminate all high fructose corn syrups and eat lots off veggies, and no fast food. Enjoy and don't bow to temptation."
