phentermine: I started taking it because I was always hungry and gained 12 pounds in the last month. With a stressful job, I had lack of motivation. Day 3 today and down 5lbs woohoo. Also working out to Julian Michaels 30 day shred. Only dry mouth, and I feel great and hunger has stalled. I have 40 pounds to go. I love this pill.

phentermine: I've struggled with weight for years and finally at my last app my doctor started me on phentermine my starting weight was 220 , three days later I was 214 I have been on it a week and haven't lost any more weight but I started watching what I ate more closely and started working out in treadmill hoping for more weight loss! Haven't really had any bad side affects , dry mouth is all I've had but I drink a lot more water and I cut out all caffeine and sugar I love the energy it gives me!

Adipex-P (phentermine): Im 5'3 and tone easier than loose. So, I started taking Adipex t 4/22 at 178 As of today 4/29 at 167 So just in 1 weeks time I have lost 11 lbs. I drink at least 64 oz of ice water a day, most the time I'm over 100 oz. The first few days I did have dry mouth, but not so much anymore. 1200 cals is what I aim for but don't always get that many since I'm not hungry all the time anymore. I've been working out 5 days a week at least 35 minutes. I just had an inguernal hernia surgery, I can only do cardio I do: 15 minutes on a cycling machine 10 minutes on a treadmill 5 minutes on the elliptical (I push myself but this is my minimum) I use the LIVESTRONG free app My Plate & I track EVERYTHING from my water, exercise, food & weight.

Adipex-P (phentermine): I started Adipex on January 15, 2013. I am 24 years old 5'5 and my weight during that time was 259lbs sadly. Today it is April 23, 2013 and I have lost 38lbs! I have tried many other diet pills but never had any luck. I have tried to exercise and watch calories without the help of diet pills but it just wasn't working for me. Yes, there were side effects high blood pressure/high heart rate (WATCH FOR IRREGULAR HEART BEAT), If so call the doctor that gave medicine. As long as I drank a lot of water the side effects decreased and was tolerable. I would recommend this to anyone who has a hard time sticking to diet and exercise. This pill has worked great for me. Drink only water, get rid of sugar. Walk at least on mile a day.

Adipex-P (phentermine): I was prescribed phentermine/Adipex for weight loss after I discussed with my doctor my lack of energy being a full time single working mother and time and motivation were really my issues contributing to my weight. She said this would give me the motivation and "want" to exercise and is an appetite suppressant. Those two things are very true. I work a desk job and cannot exercise until evening so that is hard. Day 1 and 2 I was on the go all day and felt fantastic, full of energy, and very happy. Day 3 I had several negative side effects of high blood pressure, heart pounding, fatigue, insomnia. Day 4 I had the dose cut in half by my doctor. Today is Friday, day 5, and I have lost 9.5 pounds since Monday. Hoping to see more loss but slower!

phentermine: This is great. I started the pill on 4/16 at 5.4" 172lbs now today 4/18 I am 167lbs. Thats 5lbs in 2 -3 days. I have to remind myself to eat and I walk for about 60 minutes a day. My goal is to get to 135lbs, with this pill I am sure to meet my goal within 2 months. Please be sure to eat healthy and your mouth will be dry so drink plenty of water or chew gum.

phentermine: I am 19, 5'8, & was 260 lbs. I just started phentermine 2 weeks ago. I try to exercise at least 20 minutes 5 days out of the week & eat healthy meals. So far on this medicine I have lost 16 pounds so I am currently 244 lbs. I really don't have an appetite & have to force myself to eat. Only side effect is a dry mouth and a bad taste in my mouth, but that's nothing gum can't fix! Love this medicine so far.

Adipex-P (phentermine): I'm 5'3 and weigh 196lbs and I started taking Adipex on 4/5 and on 4/8 I weighed 193lbs. The first day it made me very jittery and have dry mouth very bad. I have also walked on the treadmill for thirty mins since I started the Adipex. I have lost a pound a day. It helps me to eat smaller portions. My goal weight is 150lbs.

Adipex-P (phentermine): I am 5'1" and weighed 192.2 when I saw the doctor. Exercise and dieting weren't helping me and he was concerned the weight may be the reason why my blood pressure is high and why my PCOS has been acting out. So he put me on Adipex-P and so far so good. I have lost 5 lbs in 10 days since starting the medication. I feel super energetic too.

phentermine: I have been taking phentermine for 3 days now and have already lost 7 pounds. I have also stuck with a 1000 calorie diet & 30 minutes of exercise at least 3-4 times a week if not more. I am really amazed by this! Three months ago, I had my first child. I gained 60 pounds while pregnant & I felt awful! After the pregnancy, I still had over 40 pounds on me! I have tried everything and nothing seemed to work that great. This diet pill is just a miracle in my eyes!

phentermine: My husband convinced me to see a weight loss specialist when he finally got tired of hearing me talk bad about myself. Two days ago I went, got weighed in, 174 lbs... my scale said 175 but I'll take their number. This morning I was 170 lbs. Wow. This really works. I have to force myself to eat. The house is always clean. "Put the sweeper up" my husband said to me today. I feel WONDERFUL. My mood is a constant pleasure to everyone around me. My skinny jeans I wore before my car accident two years ago are gonna get on my honey one way or another! Only downside to the doctor is he's going to kick me out of the program at 155 lbs but I was 120 before the wreck and that's my personal goal.

phentermine: I am 26 yrs. old and after 3 kids in 4 years have gained 72 lbs! I became so self conscious of going out to public that I would make up excuses for why I had to stay home. Finally, I could not bear it any longer and went to my doctor. He prescribed phentermine 37.5mg. I am on my 2nd month and so far I have lost 22lbs! I am so excited! I do 30- 45 mins cardio 4-5 times a week, and strength with a healthy food plan. I know some of you said that you are losing the weight without exercising, but I'm afraid of flabby ugly looking skin so I'm trying to stick to a lot of toning and cardio. I'm actually trying to do more workouts to hurry the weight loss along! The only side effect I have is the dry, fuzzy mouth. I really am glad for this!

phentermine: I am 56 years old and have done every diet out there plus I was even a director of a very popular weight loss company. Even there I struggled with the cravings and getting the weight off. After I quit I started to gain weight once again. I was so disgusted with myself once again! I saw a doctor thinking here I go again, struggling, craving. Why does nothing work? The doctor listened to me and recommended phentermine. The very first day I thought can this be real? The cravings were gone! I was actually thinking of other things beside food and what I was going to eat next! It felt like a miracle! 2 months later and it still feels like a miracle! Why didn't doctors over the years ever tell me about this before? Find a good doctor!

phentermine: I have used Phentermine after both of my babies to lose the baby weight. The first time I lost 30 pounds in 5 months. This time it has only been 8 days and I've already lost 11 pounds! I have never experienced any negative side effects, I am thirsty and drink a ton of water, I have zero appetite so I have to force myself to eat, but I also feel energized, focused and extremely happy while on Phentermine. I always recommend this to my mommy friends who want to lose their baby weight as well.

Review by bclyn13 (taken for less than 1 month):

Adipex-P (phentermine): I have been taking Adipex for 4 days now. I have lost 13 pounds somehow. I changed my eating to only in taking 1000 calories a day. I take half a pill in the morning and half a pill at noon. I have severe dry mouth and drink about 10 bottles of water a day. I am having trouble sleeping for the last 2 days. I get the jitters really bad about 30 mins after I take the pill, it lasts for a few hours. No issues with my heart rate! I am hungry until my stomach hurts I was a over eater so its pretty painful! With all that this pill is worth it I am excited about my progress so far and can't wait to see what I can get down to in a few months!

phentermine: I am not obese, just about 20 lbs overweight. My problem with weight loss is not really what I'm eating but how much I eat and a lack of motivation to exercise. Side effects of phentermine you feel like you are on a constant adrenaline rush and will want to do everything! I advise starting off with phentermine on the weekend to see how you react to it, rather than on a workday. I only take half a pill, and it's pretty powerful. Also you will be thirsty all the time, so drink LOTS of water. You will lose weight very fast, because you won't really eat, and will be running around. REMEMBER: this is NOT a magic weight loss pill. You use phentermine as a stepping stone to change your habits. If not, all the weight will come back once you stop.

phentermine: I did lose 8lbs in a month but my blood pressure is HIGH! I am usually in the 120's. But went for my follow up with the Dr. and it was 149/95! Checked it the next day and it was 145/75. Stopped the pills for 2 days and my BP went down. I took the phentermine today and checked my BP 2hrs later and it was 148/102. It does help lose weight fast, but I don't want hypertension. I am 5'6 and now weigh 177lbs. Will keep on my high protein diet. Just beware of the side effects. Monitor your blood pressure.

phentermine: I agree, the best medical weight loss pill out on the market. What made me feel safe was knowing its been around, FDA approved for 60 years. I've been on phentermine for a month and a half now and already reached my goal of 135. I lost a total of 20 pounds! I recommend to anyone wanting to lose weight fast.

Review by Selena T. (taken for less than 1 month):

phentermine: I went to my PCP and they told me that he wouldn't prescribe me phentermine, I just need to work out and changes my eating habit, which I tried for 6 weeks and only lost 10 pounds. My friend referred me to another office, who prescribed me phentermine and I lost 25 pounds in 6 weeks. Now I am down 35 pounds with the help of phentermine, eating right and exercising.

phentermine: I have been on phentermine exactly a week today and have lost 6lbs! I go to the gym 5 times a week for 45 min to an hour. Only side effect is dry mouth. I want to lose 25 more lbs so I'm sure I'll be at my goal by summer.
