For Weight Loss (Obesity/Overweight) "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 now I'm 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 lightheaded, 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."

For Weight Loss (Obesity/Overweight) "I began taking Adipex in August 2008. I have been sticking to my doctor's weight loss plan of a 600-calorie per day diet. It has been 6 weeks, and I have lost 23 pounds. I feel so much better and plan to continue Adipex and my diet plan until I reach my goal weight. When first beginning Adipex, I had some trouble sleeping and found that I was dizzy often. Keeping some hard candy in my purse to eat when feeling dizzy seemed to help level out my blood sugar. After the first couple of weeks, sleeping and dizziness troubles went away. I feel that with the amount of weight I have already lost in a short amount of time, this drug is totally worth any and all of the side effects that I experienced."

For Weight Loss (Obesity/Overweight) "I am a 42-year-old woman, 5'0" and weigh 232 lbs. I am way too short to be this heavy. Severe depression over the years brought me to this weight. Today is my first day on Adipex 37.5. I took 1/2 pill after having my morning smoothie. I am doing Dr. Oz Day Off Diet along with this. So far, so good. I only felt a bit of a head rush, but otherwise, the energy is perfect. I'm giving myself until January of next year to complete my full weight loss of 107 lbs. I will be walking every day as well. I will check in with updates every Monday. Hope I can help folks here as well."

For Weight Loss (Obesity/Overweight) "I am 5'3, and when I started Adipex in late January, I was 202 lbs. Just now starting to slowly stop taking them by skipping days. I have had a total weight loss of 38 lbs in 3 months. The first month was the quickest results. I've eaten 1200 calories daily, drank water, and worked out extremely for 4-5 times a week. Experience headaches due to lack of water sometimes. I was dizzy when standing up too fast, had many sleepless nights from too much energy, even though my body was so tired. But I feel reborn. I feel so happy and confident. Of course, my body image isn't what I expected, but my journey has not ended yet. Adipex is a tool used to help change your lifestyle. I can't wait to say I changed my lifestyle and no longer need a pill, but I am thankful for it."

For Weight Loss (Obesity/Overweight) "I have been on Adipex for almost two years. When they say it's not such a thing as a miracle pill, they haven't tried this. I lost 10 pounds from my goal of losing 150 pounds. My weight loss has slowed down a bit, but as long as the numbers go down and not up, I'm still happy. I did experience extremely dry mouth, dizziness, and loss of appetite for the first two months. BUT IT WAS WORTH EVERY BIT. Now I'm starting to have sleeping problems, which I don't like. I am very scared that if I stop taking it, I'm going to gain my weight back."

For Weight Loss (Obesity/Overweight) "I work at an endocrinology clinic. And there, I have seen crazy stories about Adipex - from 191 lb in 1 year to 30 lb a month. So, I said to myself I'm going for it. In the first 3 days, I am 4 lb down. I have plenty of energy, I do have a dry mouth, and one time after I stood up from the bed I felt dizzy. Now, my post is more for the people who are taking it - please take 1200 cal per day. If you take less, you will have jitters, and you would start doubting the medication. And yes, I push myself to eat because I want to eat, but I eat small portions. From day one, I want to adjust my portions, always small portions. After 1 month after my medication finishes, I will continue small portions and won't exceed 1200 cal. Good luck."

For Weight Loss (Obesity/Overweight) "I started this medication on 3/4/16. Starting weight was 208. After a week of taking it, I've lost 10 lbs. I weigh now, is 199. This pill works! I've been eating small snacks and working out. So far, the only problems I've experienced are dry mouth, dizziness, restlessness, and slight tremors for the first few days. I'll give an update in about a month."

For Weight Loss (Obesity/Overweight) "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 nauseous and dizzy at times."

For Weight Loss (Obesity/Overweight) "I started Adipex on June 28th. It is Sept 25, and I am currently down 21 pounds! I started at 246 lb, now at 225 lb. I do light exercises at least 3 times a week, and I try to stay within 1500-1700 calories a day. The Adipex helps by curbing my appetite. I have experienced some dizziness if I don’t eat enough breakfast with it. It also causes dry mouth, so I would recommend always having a bottle of water around. I would say it has been immensely helpful as I am trying to form new healthy eating habits, more than I have been able to do on my own in the past. Best of luck to everyone trying to create a healthier life for themselves!"

For Weight Loss (Obesity/Overweight) "I have been on Adipex for 2 weeks now. I do have some sleeping problems, but it is getting better. I have had some dizziness also. I was 246 lbs, and at my 2-week weigh-in, I was 235 lbs. I have changed the way that I eat and have had no time for exercise. I love this pill."

For Weight Loss (Obesity/Overweight) "I started taking Adipex on 3/21/12. My starting weight was 271.5. Today is 4/25/12, and I weigh 258 lbs. I've lost a total of 13.5 lbs. I'm certain I could've lost WAY more. After over a month, I still have 1/2 a bottle left. The side effects of the pill (rapid heartbeat, dizziness from not eating, etc.) brought out my pre-existing anxiety issues. I stopped taking it for 2 weeks and got back to eating wrong, but I started again a little over a week ago, and I'm losing like CRAZY! I weigh every day, and the number keeps getting smaller (side effects are GONE). I sometimes skip a pill, but I still don't feel like I'm starving like I used to. I will continue to take it until I reach 145 lbs. I haven't exercised, but I did purchase the INSANITY workout and will start soon."

"I am down 13 pounds in 10 days of taking this medication. Haven't eaten much since starting, so I'm pushing the fluids to keep hydrated. No exercise, but I'm a mom of 4, so I'm kept busy running around after kids. Jitters, insomnia, dry mouth, and dizziness are some side effects I've had, but hoping that my body adjusts to the medicine soon."

For Weight Loss (Obesity/Overweight) "I'm 19, female, 240 pounds, and 5'8". I started taking Adipex yesterday (02/10/2017), and I had a boost of energy for about 5 hours, along with constantly sweating, dizziness, no appetite. I had to force myself to eat, and my heart racing and blurry vision here and there. I sure do hope to see results because these side effects are pretty terrible. Any recommendations? I'm drinking lots of water and eating with the pill."

For Weight Loss (Obesity/Overweight) "I used Adipex for 3 months, lost 30 lbs the first 2 weeks. I had side effects of dizziness, sweating, insomnia, rapid heart rate, but I had a lot of energy, and the side effects only lasted 2 weeks. I cut back on going out to eat, and ate Lean Cuisine, drank only water or coffee with sweetener or unsweet tea. This pill is amazing, and I can't wait to go back on it again in 6 months! Cost was only $40.00."
