For Weight Loss (Obesity/Overweight) "I started taking Adipex on November 17, 2009. It is now January 25, 2010. I have to admit when I first started taking Adipex, I felt like I was on straight speed. I couldn't sleep, eat, or concentrate. I still have bad mood swings and get upset very easily. I have no problem sleeping, that wore off the 3rd week. I tend to get hungry later in the afternoon. I was taking a half of a pill the first month. I take one pill a day now and do great, except for my mood swings. My starting weight was 165 lbs. I now weigh 138 lbs. That's a weight loss of 27 lbs. I still have 8 lbs to go. I exercise 5 days a week on the treadmill for 30 minutes each time. If you are really wanting to lose weight and can overlook the side effects, this is the pill! Good Luck!"

For Weight Loss (Obesity/Overweight) "Oct. 16th - 5'8, 256 lbs, Male. Oct. 26th - 240 lbs even. 16 lbs - 10 days. Loss of appetite, which makes it easy to control how, what, and when you eat. Dry mouth only if you don't drink lots of water, which is absolutely necessary to dispose of the fat you're losing. 1/2 pill - modest energy. Whole pill - a bit shaky, but I love shaky. Feels like a miracle is happening. Getting my life back slowly but surely."

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 started taking Adipex-P on August 15, 2008. I weighed 177 lbs. It's been a little over a week, and I can tell that I've lost weight. I haven't weighed myself again, but I can tell by the way my clothes fit. My appetite has changed since I began taking the pill. I will weigh myself next month on the 15th to see how much I've lost. I highly recommend this pill to anyone who wants to lose weight."

For Weight Loss (Obesity/Overweight) "Started taking 12 days ago, starting weight of 256.6 lb & today 250.0 lb. Side effects: increased energy which I absolutely love, suppressed appetite which is good, dry mouth which means I drink a lot of water which also is good. Considering I struggled with drinking enough water daily, this changed that. I still get hungry, but only 2-3 times a day, once I start to eat, I'm full very quickly. A simple snack like fruit or raw veggies quickly takes the hunger away. I eat a sensible dinner with the family. I've completely lost interest in soda & sweets. I do take a multivitamin. Stay smart, watch what you know you should be eating, exercise & live healthy. You can do it, this helps."

For Weight Loss (Obesity/Overweight) "Day 4, taking 1/2 tablet of the 37.5 mg. 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."

For Weight Loss (Obesity/Overweight) "My doctor prescribed Adipex on Oct 5th, 2012. I was at 287 lb, 5'8", and 57 years old, struggling to lose any weight but nothing. Together with the Adipex, my doctor gave me other instructions, like what to eat and also to exercise. I have had no kind of side effect unless you call no appetite a side effect. I make sure that I eat at least 1,200 calories daily. I also exercise for 1 hour and 10 minutes every day, 7 days per week, no excuses, no nonsense. I find that when you make up your mind and heart, everything was good. I’m at 236 lb, I have the energy of a 25-year-old, I’m looking better and feeling better. Soon I’ll reach my goal of 180 lb. Feb 23, 2012."

For Weight Loss (Obesity/Overweight) "The first day I took this medicine, I had so much energy and was extremely focused. The second day was a little different (I am prescribed the dosage of 37.5 mg/day). The second day, my appetite was gone all day, and toward the later afternoon, I started throwing up. I could not eat any food that day. Now comes day three, I take the medicine again, hoping that I wouldn't have the same reaction as the day before, and I was right, but everything worsened. I still haven't gotten my appetite back, and I've thrown up seven times today and cannot hold any water or anything down without throwing up two minutes later. I haven't had food in two days because of the constant nausea and vomiting. If you have a sensitive stomach, beware."

For Weight Loss (Obesity/Overweight) "I started taking this pill because being on depo and an office job has caused me to gain a ton of weight. I will update weekly. Because the first week I have seen a huge change. My energy is back. I don't want to sleep all the time. My focus is back. And I am driven. I have cut out all pop, started watching the calorie intake, and I am actually pulling my kids in a wagon every night. We have now extended our walk, and I feel great. Starting weight - 6/20/17 - 324 1 week weight - 6/28/17 - 317 (-7 lbs)!!! I could not be happier, and I know I am living a healthier lifestyle. Without this med, I don't think I would be able to do it. It suppresses my appetite and boosts my energy. Good luck to all."

For Weight Loss (Obesity/Overweight) "I just started Adipex on June 2nd, 2015. I weighed 194 at 5'8. I do have some side effects, I have the shakes, dry mouth, and I'm not hungry at all. I'm not going to weigh myself until I go back to the doctor on July 1st, 2015. I work midnights, so I'm not very active, especially with my profession, but I'm definitely excited to see results and go on to be happy with my life. :) Will post an update in July."

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) "Have been taking Adipex for almost 2 weeks. The first week I did notice an energy surge, but now I'm back to my normal levels. I have no appetite in the morning, a bit of an appetite for lunch, and have to watch what I eat for dinner. I vigorously exercise for 60 minutes 5 times a week. I have lost 10 lbs so far. I am glad for the help with the appetite, but am always contemplating the pros and cons."

For Weight Loss (Obesity/Overweight) "The first day, it was great! Did not have an appetite. In a week, I had lost 4 pounds. After 2 months, it gives me energy for 7-8 hours. Then, I crash and eat everything in sight. Doctor says-be patient. Crazy way to live. My other meds all make me gain weight!"

It may not be very healthy, but I'm happy with the results. Also, it's a great energy booster and my days at work go a lot faster!"

For Weight Loss (Obesity/Overweight) "I have been on Adipex-P for 1 week now and have lost 5 lbs. I have experienced loss of appetite, dry mouth, headaches, nausea, jitters, loss of memory, and have a bad taste in my mouth. I'm pleased with the weight loss, but the side effects are bothersome, so after I am done with this month's supply, I'll stop. Starting weight 181 lbs."

For Weight Loss (Obesity/Overweight) "Only 2 days in, and I have zero appetite. I am focusing on weight lifting rather than cardio for my exercise, and I have to force myself to eat so I get enough protein in, otherwise, I truly believe I wouldn't eat a single thing all day. And even then, I'm extremely stuffed after just a few bites. I do get a bit jittery for an hour or two after taking my pill. I've also experienced what I'll call 'pent up energy.' I don't get energy like I want to run around cleaning the house, it's an energy like I want to go lift heavy weights. I would almost say it's an aggressive energy, but in a violent or mean manner at all. I hope this continues to work as it has these first few days. If it does, I'll reach my fat loss goal in no time."

For Weight Loss (Obesity/Overweight) "I just started Adipex on 8/20/10. I haven't weighed yet, but I will on 9/02. I will post my results. I currently weigh 195 lbs, and I'm 5' tall. I had my daughter about 2 years ago, and the weight never left. I kind of jumped on in. I bought about 10 bottles of water at 8 oz, so I can drink them daily. I start walking in the morning and cardio in the evening. I will keep that up for two weeks to see results. If my routine works, I will keep going. The first day I took it in the morning about 30 minutes before I ate a bowl of cereal, and I wasn't hungry for the rest of the day. I actually forgot to eat. Day 2 was the same way, and day 3 I had breakfast and made myself eat a light dinner before 7. I love how it curbs my appetite. That's progress. Will repost on 9/2. Stay tuned."

For Weight Loss (Obesity/Overweight) "I just started Adipex-P 37.5 mg on March 6th, 2011. I am in the military and am a single mom of two. I work and go to school full-time, so it's hard for me to work out every day even though I'm supposed to. I have never really had trouble losing weight until I started working night shift in May. I would only eat one meal a day, but since it was late, I gained the weight. I am 5'5" and weighed 184 lbs before I was put on this pill. The first day I took it was right after the doctor's appointment. By 5 pm, I had only eaten one piece of ham. I bought a salad after I took the pill and tried to eat it when I got home at 6 and couldn't because I had no urge to want to eat. It's Wednesday now, and I've lost 4 lbs already."
