phentermine for Weight Loss: I started using phentermine 30mg on 2/1/14. My starting weight was 216 (I'm 5'3")...on 2/8/14 I weighed in at 209 and on 2/15/14 I weighed in at 205 (while on my period, which usually makes me gain 4-6 lbs) 11 LBS in two weeks is soooo motivating. I was recommended the Atkins diet but I workout really hard (power lift, insanity, boot camp) so for the past two weeks I didn't do the practically no carb plan I was given, but I did lower my carbs significantly (I used to eat a lot of oats, wheat bread, sweet potato) the doctor said I'm doing great because most people my age, height, and starting weight, lose about 10LBS a month. Phentermine curbs my appetite like nothing ever has and I'm loving my results so far. I'll update next week.

phentermine for Weight Loss: I'm on phentermine for the 4th time. I told my doctor I want a life long IV drip of the stuff. It's a miracle in a bottle. It cured my sluggish tired feeling days...made me up beat, happy, motivated for daily tasks (which are many with four small children) not to mention it not only suppresses physical appetite but the all powerful emotional appetite. My brain quits telling me I need food to feel better! I've lost a lot of weight on phentermine. Here's the catch. You can't stay on it forever. Being that I'm on round four ...hopefully I can keep it off this time. I have also experienced the dry mouth and heart palpitations (hopefully harmless). Be strong when you are done and don't gain it back!

phentermine for Weight Loss: I started Jan 4th at 262lbs, weighed in at 253lbs. I hike every weekend and dont snack as much. I try to eat low calorie soups for lunch vs sandwhiches or hamburgers. I still need to modify my breakfast to a lower calorie version. So far, I'm okay with it. I need to be 180lbs and under.

phentermine for Weight Loss: I have been on Phentermine 37.5 now for a month. Prior to taking Phentermine I have tried everything! Exercise(Tae Kwon Do, P90X *with trainer* and Insanity *with trainer*), changed my diet, did everything I could to lose weight. Nothing helped! After finding out I had an hypothyroid Doc put me on some meds, and also put me on Phentermine 37.5. So after the 1 month of being on this, I have gone from 338lbs to 311lbs. At the beginning the side effects were bad! Always felt drunk, sweat all the time, couldn't sleep, and ALWAYS *even now as I type this* having a dry mouth! I have no hunger, and only know I am hungry when my stomach hurts. So, this works... just be ready for a roller coaster ride in the beginning. Good luck!

phentermine for Weight Loss: I posted a thread on January 31, 2014. I weighed in on Friday at 172lbs. I am roughly 66inches, I've been taken this medicine for a week, and I have lost 10lbs. I weighed in about an hour ago and I am 162.4 pounds. I would say, its working. My goal is to get to 157-160lbs.

phentermine for Weight Loss: I have used them since October. I couldn't lose weight needed a bit if help with the passing of my Mom. I am a stress foodie. I went to the doctor and told him I needed help how about the lap band he took my vitals my weight BMI pretty much a physical and told me my BMI had to be 40 in order to get the lap Band mine was 32, so he prescribed me phentermine. I have anxiety so I take 1/2 a day. It makes you choose better food. You eat healthy. I sleep better now than ever. Lost 40 so far.

phentermine for Weight Loss: I'm 5'3 184lbs (starting weight) I started taking this on Jan 29. Small pill easy to swallow. No nasty after taste. I take my pill when I wake which is 6:30am only because I've read reviews where they could not sleep and I didn't want the problem. 15-30 mins after ingesting the pill I also experience the jitters. Which can be easily taken care of by just eating breakfast. You're full an energy all day, the 1st day it did not suppress my appetite like I thought it would, so I went on eating as normal. Day 2 took the pill 6:30am shortly after I get the jitters, I eat my breakfast, the jitters go away. Day 2 jitters(just eat) dry mouth (drink water), energy, no appetite, and insomnia. I only got 2 1/2 hrs but felt great in the morning!

phentermine for Obesity: I have been on Phentermine 37.5 for a week. I am sticking to a 1200 cal diet, walking every night. I haven't had any bad side effects except dry mouth, but I count that as an advantage. When I started the pill I weighed 407lb and today I weigh 395lbs. I know it isn't a fix all, but I seriously needed help curbing my appeite, I don't think about food, and even have to force myslef to eat (I do make my self eat some, I want to learn to eat properly not starve myself)

phentermine for Weight Loss: I began taking phentermine on December 2nd, 2013. I also began the paleo diet at that time. I truly believe that I couldn't have maintained the diet without phentermine. I have no cravings for pizza, burgers and such. I allow myself 1 day every 2 weeks to eat whatever I please and it's hard to shovel in an unhealthy amount of food. I'm a 48 year old male and weighed approximately 178 lbs when I began. As of January 28th, 2014 I weigh 158 lbs, just 5 lbs shy of high school skinny. I go to the gym 5-6 times per week. I lift weights and do HIIT (high intensity interval training). When I look in the mirror I'm very pleased with my appearance. Not to sound boastful, but I look damn good for a man my age. My 30 - year class reunion is in 3months

phentermine for Weight Loss: I am 5'3" and I started with the weight of 140.6lbs 2 weeks later now I am 131.6 pounds. When I started taking the pills I would only drink half of the pill and would give me bad side effects like speeding my heartbeat, dry mouth, paranoia and nervousness so I skipped it one day on the first week. Then on my second week and so on my body got used to it. I've started on January 15th we'll see how much more weight I'll be losing by February 15th. I'm so excited can't wait.

phentermine for Weight Loss: I have lost 38 pounds on this since September, 2013. I am on a diabetic diet and a fitness program also. This medication has helped me a lot! Taken the edge off the hunger and helped me get my glucose levels under control. There are some side effects, but many of them went away by week 3. Metal taste in my mouth, headaches, constipation (has not gone away), and dry mouth/bad breath. This is not a miracle pill. You will have to work hard, and make good choices. My Doctor is helping me learn how to make better choices and make healthy living a part of my life. I plan on being on this medicine ONLY until I can successfully learn how to control my glucose levels and follow a plan consistently.

Adipex-P (phentermine) for Weight Loss: 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 important is to take vitamins and minerals along with Adipex. I had back pain, heart racing then even I felt like my heart stopped for 2 seconds, scary but I started to listen to my body. I drank lots of water, ate loads of spinach and leafy greens and vitamins, vitamins all the time. It is also strongly advisable not to eat any meat or heavy meals. Please remember that despite the fact that you got loads of energy, uyor bowels are sleeping, you can hardly feel any movement in your stomach. Phentermine is blocking the "hunger centre" in your brain. I hope it helps. I have reduced all side effects I've had.

Fastin (phentermine) for Weight Loss: I took a pill this morning with some tea, and while I was eating breakfast I noticed my heart rate sky rocket, I don't know if this happened because I took fastin on an empty stomach or what, but this is a little scary! It literally feels like my heart is going to jump out of my chest! At first I didn't think I could be reacting to this drug so quick but apparently it's a very quick release type of pill. I can say that I'm not hungry and didn't finish my breakfast but at what cost?! Maybe I should try taking a quarter of the tablet, but I think I'm a little to scared and will probably throw the bottle away.. what a waste of $40 oh well better 40 bucks lost than a heart attack. Also I bought these over the counter at a Rite Aid.

Review by Mrs Motivated (taken for less than 1 month):

phentermine for Weight Loss: I have been using Phentermine for the past week and it works! I already lost 7 lbs in 1 week with diet and exercise as well. In the beginning I was very apprehensive about this. I have friends who have used it and it also worked for them. I did experience a few side effects such as: dizziness, heart palpitations, and insomnia, but once my body got used to it I felt fine. As a nurse, mother of two, and I juggle two jobs Phentermine gave me the energy I needed. When I left work @ 5pm I would pick up the kids make dinner, do homework and still have energy for an 1 hour and a half, 5-6 days a week of exercise at the local 24/7 gym. So thumbs up Phentermine!

phentermine for Weight Loss: I lost 23 lbs in 2 months. It really works guys if you don't have any thyroid issues. It also gave me energy and made me sleep less, which was a plus because I work a night shift job and have two small children. I also got a little high off of it the first two weeks on was on it. The best high ever. Oh and by the I had the best orgasms ever in my life.

phentermine for Obesity: I am 33 yrs old 5'8 weighing in at 276lbs, lost 106 lbs on my own eating low carb back in 2008. Gained most back pregnant with our 5th child 2011. Then my thyroid went nuts (postpartom thyroiditois) and gained 40 lbs in 2 months after baby. Thyroid straighten up but weight remained. Low carb dieting just wasn't working this time so I got desperate & doctor put me on this phentermine 37.5 a day. I started on Dec 18th 2013 & in 3 days I've lost 8lbs. I have to make myself eat even though I have no appetite. I can barely get 700 calories in. I feel light headed and thats all so far. I eat very healthy now. I hope I'm eating enough.

phentermine for Weight Loss: I started taking phentermine 2 1/2 months ago...thinking I weighed around 250lbs I decided to go to a weightloss clinic. At my 1st appointment I couldn't believe I actually weighed 336 lbs. I am 5'4 and 24 years old. I go to the clinic every Saturday to get weighed, get a B12 shot and also they give me my medicines for 1 week. The phentermine, amino acids, calcium, and a multivitamin. So after 10 weeks of a strict protein diet and at least 2 hours in the gym everyday I am now down to 269lbs. That's 68 pounds in 2 1/2 months. I wouldn't be able to stick to my diet without the phentermine. It definitely suppresses my appetite.

Adipex-P (phentermine) for Weight Loss: I started taking Adipex in Sept and went in on Dec 7th for my three month check in and I lost 38 pounds. I am 5' 8" and began weighing in at 259 and am now down to 221 and this is without including exercise. Walking is part of my daily routine, I walk a lot throughout the day as I'm running between classes and then to go to work. I did experience some side effects the first week like being light headed, dizziness and a dry mouth. But I use that to increase my water intake. My doctor actually recommended I only take it about 5 days a week so that my body doesn't become so used to it and that's what I have been doing. So far, so good and I can't wait to continue losing weight.
