For Weight Loss: I'm a 24 year old single mother, and diet and exercise was never in my vocabulary. However, I am the heaviest I have ever been. (weighed less when I was 9 months pregnant). I have taken phentermine 37.5mg once before and I had no idea what to expect. I know that this is not a magic pill, but more of a booster. I've lost 25 pounds within a month, worked out, ate less and consumed more water and cut out sodas and fast food. Was able to wear smaller clothes and the confidence came back. I'm back on it again starting yesterday 7/17/14, and hope I get the same results as last time. My side effects were dry mouth, feeling a little more irritated, heart was going fast, the feeling to constantly move. Smoked constantly. Good luck everyone

Adipex-P (phentermine) for Weight Loss: I started taking Adipex on July 15, and I must say I have definitely seen a difference in my eating habits and it's only been 3 days! Amazing! I was 127lbs in 2012 and somewhere along the line I lost the will to work out and stay fit. Needless to say I gained about 35lbs since then so I am giving Adipex a try and it's doing wonders for my appetite! I experienced dry mouth the first day and that's the only side affect I have had. I eat a yogurt for lunch and dinner is 2 turkey sandwiches on wheat bread, and I drink 2-3 bottles of water a day. Eating right and exercise are key to helping drop weight quicker! Once you stop taking the pill you must maintain good eating habits along with exercise or the weight will come back plus more!

For Weight Loss: I can really say that I was nervous starting this pill because I read the reviews and didn't want to experience the side effects. I just started this pill on Tuesday, 7/8/14 and it has now been exactly one week and one day. I started weighing 188.6 and as of today, Wednesday, 7/16/14 I weighed in at 180.4. So that makes a total of 8.2 pounds lost in just one week and and day. I normally work out but I didn't work out for this entire week purposely just to see how much weight I would lose without my daily exercise. I did however maintain my healthy meal plan and I drink 1/2 to 1 gallon of water daily. I am 25 years old and 5'10. I haven't experienced any side effects (knocks on wood so I wont begin to experience them, best wishes to all!

For Weight Loss: In my last post, I had lost 8lb in 2.5 weeks. Starting weight was 181lbs, I currently weigh 168. I have been on Phentermine for about 6 weeks. I have had a busy summer, in which I would usually gain weight however, I have continued to lose even though my busy schedule makes it hard to work out every day. Currently down 13 lbs! I will begin to increase my workout schedule as I am not as busy anymore. Hoping to lose another 10-15lbs within the next 8 weeks (maybe more!).

For Obesity: I started this pill in late Feb 2014 and my starting weight was 224lbs. I haven't been faithful in taking it I've missed many months due to the fact that it's very expensive. But, since taking it and along with cutting back on how much I eat (haven't really exercised) I'm down to 186lbs. There's a huge difference in my appearance and the way I feel. It's also given me more energy. The only downside is that when I'm not using the pill I don't have much energy but that might just be me. I didn't gain while not taking it either.

Adipex-P (phentermine) for Weight Loss: I have been on this medicine for nearly one week. I have lost 8lbs since starting this medicine. I take half a dose on a empty stomach and then drink protein drinks both for breakfast and lunch. Then eat a light supper and been eating about 1100 calories or less a day. I go to the gym about 3 to 4 time a week. I have noticed every day a change in my weight. I haven't had any side effects my blood pressure been running great. I don't experience any nausea or vomiting with this medicine while working out. I am planning taking this medicine for 1 month and then taking rest and start it again.

For Weight Loss: I was prescribed Phentermine for weight loss as I was about 70 lbs overweight. I'd been struggling for 18 yrs with depression and anxiety from a traumatic event and even though the doctors prescribed antidepressants and anti anxiety meds, I still felt lost and sometimes suicidal. Within about 20 minutes after taking my first phentermine pill, I felt absolutely "normal" again. Imagine 18 yrs of struggling, not being able to focus, falling behind at work and at home, losing track of my thoughts and not able to hold a decent conversation then a weight loss medication gave me back my life. As for the weight loss, I changed my eating habits, stopped drinking soda and lost 18 lbs within three months.

For Obesity: I have been on phentermine for 16 days today and have lost 15 pounds. I too have cut out carbs and usually walk 3 to 4 times a week! The only side effect I've had is the dry mouth, just drink a water and everything's fine. Can't wait to see my results after a couple months.

For Weight Loss: My experience was successful! I started the pill on 03-26-14 at which time I was 287 lbs, by 04-30-14, I dropped down to 276 lbs. I must say it really suppresses the appetite and I recommend that you eat at least breakfast daily to avoid getting headaches and feeling nausea. Altough, I did have those side effects, I do recommend eating something again as stated preferably breakfast. The last time I weighed myself I wore 266, however, because I am no longer eating healthy and taking the pill when I remember to take one I notice I have gained some of the weight back as my pcp indicated I would. All in all Phentermine is great if you are going to adjust to permenant lifestyle changes / eating behaviors.

Adipex-P (phentermine) for Obesity: I gained 57 pounds since Oct. 2012. I was in a accident that broke my legs and was also in a unhealthy relationship with a food addict. I am just starting this medication but feel great. I am on a strict diet and exercise program plus drinking 80oz of water a day. I am hoping I will be back to my normal 125-130 self soon!

For Obesity: I was seen by my Dr. on June 30th and she stated I was overweight due to my current height. I was in the obese stage. Anyways I've started taking this medication on July 1st, starting weight 198.7 and as of July 7th I weigh 190. Within 7 days I've lost 8.7 lbs. I can not believe these results. I can just imagine the weeks to come. I extremely excited and I'm looking forward to this new lifestyle.

For Weight Loss: 4 and half weeks in, starting weight 14.3 now weighing 13.5 nearly lost a stone. Haven't changed my diet dramatically just make sure I have breakfast every morning, starting to feel hungry again now though as still on 15mg. I'll see my doctor in 2 weeks hoping for next dosage.

For Weight Loss: I have a great before and after picture that I can't post on here, but in two months on phentermine (first month 15mg, second month (30mg--and I'm not even done with this month's bottle!) I have lost 19lbs. I am trying to make wise food choices and I hike, but as a single mom I don't have loads of time to go to the gym etc. I feel so good about myself. My goal is to lose 35 more lbs to reach 150lbs and then maintain that. Honestly, I eat breakfast, and then I nibble here and there, but I'm just not hungry at all. The dry mouth is pretty rough, including the horrendous breath it causes (I carry gum and little mouthwash bottles). I'm also on Wellbutrin 300mg for clinical depression, but I was on that for months without a single pound lost.

Fastin (phentermine) for Weight Loss: I took Fastin this morning and within 30 minutes, my heart was pounding so hard I thought I was going to throw up. I don't like the way it made me feel.

Fastin (phentermine) for Weight Loss: I started Fastin 30mg from my doctor on May 19 2014. You need to change your lifestyle not just pop a pill and be done with it. Because if you don't change, the weight will return. I started at 285lbs in one month I lost 25lbs and feel great. I changed myself with habit changes and exercise. I told myself that when this weight is gone it's staying gone, so I change my lifestyle and you can do the same.

For Obesity: UPDATE I started phentermine 1 month ago and have gone down from 250lbs to 229lbs. I exercise 3-4 times a week for an hr usually 25min of T25 and 35 mins or more walking/running my cardio has gotten much better since I started and I can admit I think I've become a workout junky. If I don't exercise for a day or two I feel guilty. Anyhow I've also changed my diet completely. I'm on the low carbs diet and it is'nt so bad one cheat day which is Sunday and I count calories also I still eat bread but only 100% wheat bread hopefully once I reach my goal weight which is 139lbs I can keep my exercise and WEIGHT.

For Obesity: Started 6/1/14. Down 18.8 pounds. Highest weight 385lbs. Because of how big I have gotten and some knee and foot injuries, I've not started exercising yet. I want to loose a little more so I can feel like it. But these pills...the first week I could have moved mountains. I had so much energy and insomnia. But that has subsided. I take 37.5mg A half a pill 30 minutes or longer before breakfast. Another half depending on what time I have gotten up, and another half about an hour before supper. If I don't take that last half pill I won't make it until bed time. And right before bed is when I ate the most. No cravings. No sweets or snacks. Only 3 meals a day. I do get hungry. But as long as its working a little hunger ain't going to bother me.

For Weight Loss: Age: 25 Sex: Female Build: Athletic, Muscular Height: 5' 0" Starting Weight: 178 Current Weight: 164 Time On Phentermine: 28 days Progress: I have never been a smoker, alcohol or caffeine drinker, or red meat eater. For the past 8 months I do 3 days strength/weights &4 days cardio, spending 6-7 hours per week at the gym or outside activity like hiking. It was puzzling to me as to why I hadn't lost a single pound. Got bloodwork &results were PERFECT- no diabetes, no high cholesterol, no hypoactive thyroid, no high blood pressure. Doctor prescribed Phentermine & in 1 week I lost 11lbs! It seemed this was a "magic weight loss pill." Weeks 2, 3, and 4 I only lost 1lb each, bringing my total 1 month loss to 14lbs. 2 months to go!

For Weight Loss: I started in May and lost a total of 20 pounds starting weight was 205 now is 185. My doctor wants me to get to 160. 25 pounds more to go. I don't really exercise but I'm on my feet all day. I take it sometimes in the morning if I know I'm going to have a busy day. If I'm not I take before work at 3 pm. Side effects dry mouth so I drink a lot of water, that really quinces my thirst but I'm using the bathroom a lot because of drinking so much. I don't eat that much and I try to stay away from sweets, soda, candy and Alcohol. So far so good. Good luck everyone.

For Weight Loss: Im 19 years old, 5'3, female. I started taking phentermine in January of 2014. Lost about 12 pounds that month; I went from 180-168. I didn't really exercise like I should've nor did I change my diet which I regret because a notice that the first time you take it, is the first time you drop the most weight. I bought some again on June 12. Starting weight 168 lbs. it's now June 18th weighing in at 163lbs. I work out about 3-4 times a week and started watching what I eat. I completely cut off fast food, sugary sweets, any type of chips, etc. That's 5 pounds in a week which is amazing and I've also lost inches! My goal is 140-145lbs.

For Weight Loss: I have been taking Adipex 37.5 mg for about a month now. Eating low carbs and more veggies and protein. I eat around 1,000 calories. 5'3" 144 pounds. So far I've lost about 11 pounds and 10". I walk 2 miles everyday. Side effects: dry mouth and constipation (off and on). I worry about the heart valve side effects I've read that other people have had from taking this but I'm hoping to just have to take it for another 2 months or so. I would like to get down to 125 pounds. I do find that the Adipex helps me during the day although I still get very hungry at night. But I fight it by drinking more water. Good luck to everyone in their weight loss.
