Adipex-P (phentermine) for Weight Loss: Day 4, taking 1/2 tablet of the 37.5mg. Decreased appetite, more energy, some dry mouth here and there. I've noticed at some times a decrease in concentration, like a foggy feeling. Nothing too bad, but a little off my baseline. Haven't weighed since day 1. Hoping to lose 15 lbs this month. I like that I don't feel "cracked out" but I am hesitant to up my dosage yet. I'll keep taking the 1/2 tab until I get really used to it. Once I reach my GW I plan to wean myself off in the same way. Will update. -BusyBE

phentermine for Weight Loss: I am 61.5 inches and I weighed 179 at the first Dr. apt. for 41 years old that is not a good place to be but with the medication I am hoping to drop 30 - 40 pounds... First day I had absolutely no appetite, was awake longer than normal but I did finally sleep. Day 2 I still had no appetite but I did force myself to eat little bit easier of a time sleeping still up later than I wished but once I fell asleep I was out. Today is day 3 and I weighed myself and I am down 173lbs, 6 pounds in 3 days I am Ecstatic! I have been exercising by doing Zumba and lifting weights it is amazing to me how much energy I have. I can do an hour of Zumba. I sweat like crazy so you need to remember to drink a lot of water. Hope to meet my goal in no time.

Adipex-P (phentermine) for Weight Loss: I love love love Adipex! It took me about a week to get used to all the side effects but when you realize how much weight you are losing the side effects aren't even in your mind anymore, I started taking Adipex Jan 24th 2014. Weighing 210 pounds. Today is now Feb 19th not even a month later and I now weigh 185. That is 25 pounds down in just one month. I work out (run a mile, ellipitical, 20 min abs) 5 to 6 days a week and I only eat 1000 to 1300 calories a day! This pill is amazing and everyone needs to try it, that is wanting to lose weight.

phentermine for Weight Loss: Really has not reduced my appetite. I have tried this for 30 - 90 days, 3 different times. I also get a side effect that is not listed, but after the 3rd time using this, I'm 100 % sure that it causes a sensation of burning on the tip of my tongue. It stops after a few days of not using the medication.

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.
