Fastin (phentermine) for Weight Loss: "Today is March 26, 2016. Today was my first day taking fastin, I was scared out of my wits when I first tried one this morning before breakfast, I waited for all the bad adverse effects that I had been hearing about, but nothing bad happened even after my second afternoon dose. It made me kind of sleepy for the first hour or so, then my energy kicked into overdrive! No side effects what-so-ever, unless not eating is a side effect. I can't wait until in the morning for day number two! I'll keep you guys posted...keep in mind I kept clear of all caffeine, because these things are loaded with caffeine as is. I didn't get a chance to weigh in yet, so I'll update you on my weight also."

Adipex-P (phentermine) for Weight Loss: "Hey everyone! I started taking Adipex-P on 03/12. I am 5'5 and starting weight was 315!! :( Side effects: Dry mouth. Nothing else for me. It took about a week for the pill to curb my appetite. I drink lots of water! A couple of days I cheated on my diet but I never over ate like I used to. I have changed my eating habits tremendously. Currently I have not done any exercising but I plan to start. Today is 03/24 and I have lost 8 pounds! This is just the beginning on my weight loss journey. I recommend this pill."

For Obesity: "I'm taking Phentermine 30mg capsule, 3mths only per morrow makes 3wks & I lost 10lbs. I eat smaller portions of my normal foods, like a 1/4 of what i used to eat. I only eat dinner, No breakfast, occasional turkey/cheese sandwich for lunch, night dessert a pudding cup or something similar. My appetite decreased ALOT however some days I feel it doesn't work as well as others, I'll find myself hungrier than usual & craving sweets. I haven't done any exercising but i plan to start to increase weight loss. Wk1 I had lots of energy, wk2 energy level died down, but at least I'm not as tired as I used to be. Insomnia has gotten better, 1 nt I stayed up All Night & went to bed @ 10am nxt day! Uggh what a nt. Never had high BP but now I do."

For Obesity: "Today is my first day taking phentermine. I am 41, weight 213 and I'm 5'5" tall. I've been huge now for a couple years, and I just keep getting bigger. The doctor said for me to take 1/2 of a 37.5 tablet for 4 days, and then increase to a full tablet each day. I took 1/2 of a 37.5 mcg today. I do feel a bit lit up, but not overly so. I purposely haven't had caffeine because I have anxiety and too much caffeine really irritates me. I don't like feeling sprung so I don't plan to have caffeine as long as I'm taking it. I do feel a little bit out of sorts, though. Not really dizzy, per se, but kind of dazed."

Hopefully This Will Work (taken for less than 1 month) March 22, 2016

7 users found this comment helpful. Did you?   Yes   No Report as inappropriate

For Weight Loss: "I've been taking this medication since 1/18/16. Today marks 6 weeks exactly. On 1/18 I weighed 190. Today, I weigh 161. I need to lose 21-36lbs to get to my weight goal. I don't exercise as much as I'd like, but I'm on my feet from sun up until sun down & have cut out sodas, snacks, fast food, juices, etc. The side effects are easy to live with when seeing the results. I have dry mouth, my hands shake, I'm easily startled, and I have difficulty sleeping. I have the obvious weight loss, decrease in appetite, and increased energy. I would definitely recommend it!"

For Weight Loss: "This medicine works. When I wasn't exercising or eating healthy. Not much happened only about 3 pounds a week. when I added walking 30 minutes 3 times a week with a healthy diet the pounds started flying off. You "CAN NOT" keep eating Pizza or other high fatty fast foods inspecting this medicine to work. Because the weight will come off very slowly. In only 3 weeks I have lost 25 pounds! My diet has been fish, chicken, lean beef, broccoli, spinach, fruit and nuts I have one more month with this medicine that I probably won't finish because it will push me past my goal of 170. I started March 4th 2016 "225lbs, today I'm 200lbs I will be 192lbs by Friday. And by April 11th 2016 I will have hit my goal or gone just past it."

For Weight Loss: "I was on this medication about 2 yrs ago and taken off after 3 days (and 5 lb less) do to irregular heart beats, now this, was told by the blood drive when I went to go donate. Was told I couldn't donate that day, next I was asked to go to the ER, but decided to go see my regular dr. Dr sent me to go getting an EKG and all was fine. 2 yrs later I asked my Dr again, now another family Dr to see if I could try it one more time. I've been on this med for about 2 weeks now, lost 12 lb. I'm shooting for 50 lb off at least, so I got quite a bit to go. I've been monitoring my heart and blood pressure n I've been OK. Side affects so far are dry mouth, insomnia, and constipation. I'm 36yrs 5'2 and weighted 219.5 when I started. I'm so excited!!!!"

For Weight Loss: "I have been on phentermine time release for 2 months. I have lost 14 pds with moderate exercise. I have not had any side effects. I go to the Dr once a month for a checkup. This is the only thing that has worked for me. I have tried losing weight in the past and even with diet and exercise nothing worked. I know I can't take this forever but I wish I could."

For Weight Loss: "I started taking this medication on 3/15. I am 36 year old female that weighed 202 lbs. I have been working out for months in a boot camp setting and instead of loosing weight I was gaining due to not keeping a proper diet. When I went to the doctor my doctor stated that I should try this as my weight was higher than she would of liked it. I spoke to a friend who had taken it and then decided to give it a try. In the two days that I have taken it I have suffered from extreme thirst, dizziness, nausea (if I don't my mini meals like I am supposed to) and insomnia. I weighed myself today and went down 4 lbs, and that's in two days. I read in the previous reviews that the side effects subside after the first week and that's what keeps me going."

For Weight Loss: "I've been on phentermine 37.5mg once daily for 9 weeks. The first week was rough: lots of headaches, irritability, with an easily evoked "fight or flight" response. Although I will say that when I was feeling irritable and unreasonably mad, I was well aware of my behavior and knew it was a side effect of the med. I also have underlying mild anxiety/depression which has gotten considerably more challenging on this med. I do take Zoloft 100mg daily. All and all between the weight loss and endorphins from exercising(30 min daily) made it a lot easier to handle. For all of my time on this med, sleeping has been challenging. I have to wait a good 17-18 hrs after taking the med before I can sleep. I tried taking half a pill and it was totally ineffective. I have always been prone to dizzy spells when standing up quickly or squatting and standing: this med intensified that effect big time. But after 4-5 weeks that side effect was much less. Dry mouth is also still very common.I don't mind as it encourages me to drink more water! All said and done, it's been 9 weeks and I've gone down 37 lbs with little effort, and I still have zero appetite. I eat because I am supposed to, not because I am hungry. The effectiveness has only decreased around 15-16 hrs after taking the pill. I am 31, starting weight 252. I am a huge fan of this med. The side effects are manageable and well worth the 37 lbs loss. Diet wise, I'm doing low carb/low fat/low calorie, I go out to dinner 1-3 times a week and drink minimal to no alcohol. I did not have any spikes in blood pressure either. The initial stimulant effect went away quickly, I just feel like my normal self when I take it. The most important part of this med to me, is that it takes away ALL my cravings. Yes it destroys my appetite, but being hungry was never the reason I overindulged in the past. This med makes food indifferent so I use it as I should:as fuel, not for pleasure. Also you will get a prescription for 3 months as it is intended to be a short term medication due to the side effects on your heart(read packet insert for details). If you have high blood pressure you cannot take this :( Feel free to ask any questions! I am in no way affiliated or endorsed by this med and have posted this review in my own accord."

For Weight Loss: "I started February 3rd of 2016, so I have been taking this medication for 5 weeks. I am 21, 5'2 and started at 259 lbs. It has been five weeks, but I didn't take the medicine consistently or eat right during the third week due to a passing in the family. I also haven't exercised at all due to the passing of my grandpa and I started my school semester when I first got the prescription. I do plan on adding exercise into my routine, but just by eating less and trying to eat better I have lost 26 lbs in a month and a half! I'm at 233. I have went from a size 18 pants being TIGHT to a size 14 pants fitting perfectly. There is a noticeable difference and only side effects are headaches and dizziness, but after water and Tylenol I'm fine! :)"

For Weight Loss: "I began taking phen on January 21, 2016. I have lost twenty pounds exactly and it has only been seven weeks. I feel amazing, and have virtually no side effects except the first three days my mouth was dry. The program I'm doing requires me to see a nurse once a week, which is kind of a pain, but I'm glad because they answer your questions, can increase or decrease your dose and obviously look at your progress. One thing to note: I am extremely active, and have an active job. I am shocked I have lost this much so quickly, and I hope they let me stay on a small dose after I lose my remaining ten to fifteen pounds so I don't blow up like a balloon right after my four months are done. I am really happy, I have never done a successful diet!!! :)"

For Weight Loss: "My experience is always abnormal from anyone. My BP goes down, I feel normal instead of fatigued, and I lose 10-15 lb per mo until they stop. It doesn't change my diet as I am not a big eater, and I always exercise. I just have a non-existent metabolism. I lose about 40 lb, and then gain it back w/o it. In VA I took it for a year, first few months every day, then I took it every other day. It kept my weight at a normal range, and my BMI was great. I wish I could take it year round."

For Weight Loss: "I have been taking phentermine for only about 4 days now. But I have lost 8 pounds. I am also taking another pill, for depression and anxiety for about a month, so I'm not sure if all my side effects are from only phentermine, but I have been having lots. I have been unable to sleep for more than a couple hours a night, a migraine on day 3 that sent me home and put me in bed all day, little to no appetite, irritability, and diarrhea for a day now. However, I've been reading that these side effects only last for a week in some people so I'm going to wait and see. The weight loss part is working so far. I've just had to force myself to eat food throughout the day. If this drug works it will be worth it."

Adipex-P (phentermine) for Weight Loss: "Okay, so I'm back. I took this pill from June 2015-November 2015.I went from 301-262... not bad at all! Well, after I stopped taking the pills I gained some back. I went to the doctor yesterday and I was at 278. I was disappointed, but not surprised because I HAVE been eating a lot lately. I was prescribed adipex again, so I will continue to update. My fiance is doing it with me this time. His weight was 209 yesterday. We both started the pills yesterday and we've been very energized and feeling really good so far. i'll check back in in a month with results! :)"

Phentercot (phentermine) for Weight Loss: "I was prescribed Phentermine by my psychiatrist because I gained 30 pounds on Saphris (which I use to help me sleep). I've been on Phentermine for over 3 months now and I've already lost the 30 pounds and then some, I've gone down 2 pants sizes with the only side effect being occasional dizziness, which is a small price to pay! I highly recommend it for rapid weight loss!"
