Adipex-P (phentermine) for Weight Loss: This pill works! I do advise that you eat breakfast wait 30 mins and drink water throughout the day. If you don't get hungry eat something wholesome. My experience with headache, and mood swings was due to me not feeling hungry, yet my body still needed fuel. Listen to your body! I'm at a weight that I'm happy with. I do exercise its my therapy. One seventy three from 205! Also it helps with my blood pressure. Eating is so much easier. I can think about what I need to prepare versus just grabbing the first snack, not so good choice that would satisfy me. Know your body, breath don't over think, be happy. This is coming from me!It helped along with small positive changes. Peace!!

For Obesity: Started four days ago. First day felt great! No appetite at all. The thought of food made me feel sick but I ate anyway so I didn't feel sick. Couldn't sleep at all. Day two was ok. Headache was pretty bad, upset stomach,jittery, slept 3 solid hours but that's it. Day three, headache, jittery, just felt weird but ate good and slept great. Day four, headache, extremely tired, sick feeling. I did have big bouts of energy about an hour after taking the pill. That's when I've been exercising. I have exercised all four days. No weight loss yet and feel like shit. I'm hoping this will all change after a few more days.

Adipex-P (phentermine) for Weight Loss: I just started taking Adipex. I think so far it's helping me a ton, I'm on 1000 calorie diet plus Adipex. I'm working out every day, this is my 5th day and I already lost 6 pounds. Adipex seems to be helping me from over eating, it seems to be helping me curb my cravings. I have no craving for sweets of any kind, so far so good.

Adipex-P (phentermine) for Weight Loss: I was personally not on this pill, but my mom was and currently still is. Though she has lost about 20 lbs in the last month or so, she has been experiencing side effects. First off, she's had severe headaches since starting the medicine. She's had extreme mood swings, and is very nauseas and dizzy at times.

For Weight Loss: Firstly, I'm 18, 5'4, and 160lb when I started. I've been on it for 3 days and have lost 4.8 lbs. I was going to hold off on my review but I experienced some side effects. This takes insomnia to another level, I would go to sleep at 6-7am just to wake up 5 hours later. These past 24 hours I have felt so lightheaded that I stayed in bed thinking I was going to faint out of dizziness and even while not moving in my bed after waking up, my heart would beat at a thousand beats per second. I drink plenty of water too. I also had unexpected diarrhea. Needless to say the side effects are STRONG. I love the energy boost though.

For Weight Loss: I've been taking phentermine for 2 months and I have lost 22 pounds. I haven't exercised just my normal active life as a mother and student. The only side effect I've had is severely dry mouth and no appetite. I literally force myself to eat something

Review by Wendca:

For Weight Loss: I started medication 4 weeks ago. The first week I was only taking half a pill. Second week went up to a whole pill. I have side effects of dry mouth, unable to sleep more than 5 hours and some constipation. With all this being said so far I have found positives of losing 11 lbs, watching what I eat, drinking more water and doing portion control. I have back and knee issues so I am unable to exercise so the weight loss will assist me so I can be active in the future. I look forward to starting another month of the medication and losing another 11. My dr. Did say she will only prescribe for 3 months so I will continue to monitor and take what I have learned and implement it in my future to continue with the 60 lbs I need to lose:)

For Weight Loss: I started the meds on Monday 2/1/15 and I have seen a significant changed in my hunger. My food intake for the past 2 days has been way less than the normal. I am following the diet plan my doctor gave me and have included an exercise plan. My only complaint is the dry mouth and lack of sleep. I've managed to get about 5-6 hours each night which has me feeling rested in the mornings. And yes I've lost 2 pounds!!!
