For Weight Loss (Obesity/Overweight) "This pill is a miracle. I started taking phentermine 37.5 on January 23, 2009. I went for my follow-up, I had lost 13 lbs by March 6th. I work out daily and eat small portions throughout the day. I haven't had any problems with taking the medicine. The only problem I have had recently is nausea. Your appetite really is gone. You have to make yourself eat. If you don't, you will put all of your weight back on. I have lost several inches. I went from a size 16 to a size 12. I'm happy, and good luck to everyone. There is hope."

Phentermine 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) "I started taking Phentermine in January of this year. I took about a month's worth (I did not take it on weekends), and by February, I had lost 20 pounds. I stopped taking Phentermine for a month or so (didn't gain any old weight back), then I got back on it this past Monday (3/19), and today I weighed myself, and I lost 5 pounds in those few days. Right now, the pill is working great, but there are some negatives. Phentermine gives you dry mouth (BAD), which makes me thirsty, which causes me to constantly be peeing. It'll give you insomnia, nausea, and an unpleasant taste to some of your foods or drinks. I would recommend NOT drinking soda or eating fast food."

For Weight Loss (Obesity/Overweight) "I was on the Adipex about 3 months ago and was very successful. My initial weight was 220. At the first 2-week follow-up, I had lost 9 pounds. I'm sure it was water weight. The follow-up, which was 2 more weeks, was 7 lbs. I then went to my third follow-up, I was down 13 lbs. I started traveling and stopped taking the med. I did experience the cotton mouth, and please don't take this pill after 11 a.m. I did that, and it had me up for 14 hours, and I was not restless. So it indeed gives you energy. I wasn't eating much because it took my appetite for sure, and if I tried to force myself, I felt nausea. However, I did join a boot camp Thursday, Sept 30, and weighed in at 225. I went to the doctor to get back on Adipex today and was weighed in at 221."

For Weight Loss (Obesity/Overweight) "Started February 3rd. Wish I would've gotten to the review that said, 'Take 1/2 in the morning, the other half at noon to start ... lol.' Within an hour, I felt a bit of nausea, with a slight headache. I may be at fault because I'm so used to drinking coffee; I drank half a cup before I realized my mistake. Pros: Definitely decreased my appetite, felt a burst of energy for about 6 hours, no craving for sugar. Cons: Headache, not a throbbing headache, but just the annoying kind *(could be from withdrawal of coffee ... I usually drink at least 2-3 cups a day). Nausea. Little dizziness, slight dry mouth. Since weight loss is 80% diet and 20% exercise, getting an upper hand on my diet is crucial. I'll come back at the end of the month with another review. 58 years old, SW 220, GW 170. I'll be happy at 180 because I start losing where I don't want. I have a muscular physique (underneath the fat ... really I do). Hormones all over the place. Stay strong, ladies (and any gents)."

For Weight Loss (Obesity/Overweight) "I started taking phentermine 03/29 at 241.6 lbs. I was 265 lbs in 2010 and lost weight naturally and went to the gym and got down to 211 lbs and got lazy and the weight has crept back up. I didn't think the Rx would work, but today 03/30 I was 237.6 after just 1 day. I worked out for 2 hrs on my 1st day and had to leave because I was so nauseous. I got a headache and nausea on day 1 and could barely eat. Today was day 2 and my head has been hurting and I've been nauseous for over 10 hrs and couldn't go to workout. I am taking 37.5 mg in the mornings. I read the headache may be hunger or dehydration, so I forced down an apple and naked chicken breast, but it was hard to get down and symptoms didn't go away. I'm gonna try to stick with it."

For Weight Loss (Obesity/Overweight) "I'm a mother of two, and my youngest is 5, so I can no longer use the baby fat excuse. I spoke to my doctor, and she told me that I am very unhealthy and I need to make a life-altering decision. I finally did, I want to live a longer life. I'm 27 years old, I'm 4 ft 11 in. March 16, 2017, was my first day taking phentermine. I weighed in at 187 lb. March 18, 2017, I just weighed myself, I'm 185. This is the beginning, and I've lost 2 pounds. When you know you've lost a pound in a day, any side effects are worth it. I'm currently experiencing dry mouth, nausea, it is definitely an appetite suppressant because I haven't been hungry. I can't wait to see the effects by next week!"

For Weight Loss (Obesity/Overweight) "Started taking them on February 27th, 2017, weighing 255 lb. At my January appt, I was at 266 lb. As of March 20th, I am down to 248 lb. I am always on my feet at work. But the nausea and headaches just started 2 days ago, and nothing is tasting good. I went from loving water to wanting to throw up from drinking it. But we shall see how this goes, goal weight is 160 lbs."

For Weight Loss (Obesity/Overweight) "I started taking phentermine 30 mg daily with a starting weight of 100.7 kg (222 lbs). 8 weeks in, I am currently 90.5 kg (199.5)! (Broke the 200-pound mark!) Side effects for me eased after a couple of weeks, but I had quite intense nausea and difficulty sleeping initially. If I don’t take it by about 10 am, then I skip that day and take it the next as usual. For me, it really kills my desire to eat and knocks the edge off sugar cravings, etc. (my downfall!) and just gives me the space to make good food choices and pay attention to portion control. I have joined a gym, as was advised, to make the most of this medication (my GP is only happy to prescribe a short course initially, plus, expensive!) and have found working out fun and really helping with the cm loss :) My next mini goal is 85 kg (187.4 lbs) with an ideal goal of under 78 kg (172 lbs)...will try to remember to post here again when I’ve finished my course, good luck!"

For Weight Loss (Obesity/Overweight) "I started the 37.5 on 10/15/16, and I felt the jitters and the nausea. I did not feel the burst of energy. I only ate 600 calories on day one. Today is 10/16/16, and I feel more hungry than day 1. I ate a total of 1,400 calories today. I did have a lot of energy....I actually washed baseboards and all. I hope it continues to curb my appetite. So far, no bad reports."

So far, I haven't been very hungry, however, as soon as I ate lunch, I felt like I crashed but was still wide awake. So far, I have had some dry mouth, a headache, and nausea. My husband went through the same thing when he first started. Hopefully, it goes away quick!"

For Weight Loss (Obesity/Overweight) "Today is my first day taking it. 7/29/15. I am a 22-year-old female and weigh 270. I have exercised and ate clean plenty of times where I would lose about 20 pounds each time but would lose motivation and gain it all back plus more. I asked my doctor about this after being on Qsymia last year and hearing some friends talk about it. I take half a pill in the AM before breakfast and the other half between 1 pm and 2 pm. I didn't have any headaches or nausea. I was very energized all day at work. No dry mouth so far either. I'm going to check every week and see where I am at. I know it's no miracle pill, but the doctor said it would be a great jumpstart to a new me. By the way, I have already changed my eating habits before starting this."

For Weight Loss (Obesity/Overweight) "43 yr old female. I started phentermine 37.5 mg once a day on March 14, 2017. I lost 10 pounds as of April 12, 2017. Today is April 27, 2017, and I have lost 18 more pounds in 2 weeks. Total of 28 so far. I have no appetite at all, really. But I was starting to get dizzy and nauseous. Severe stomach pain, so I force myself to eat small meals. I do notice that I'm constantly thirsty. Easily agitated or annoyed also. But other than that, I like the results."

Today is day one, 37.5 mg... It's midnight and I'm still wide awake with a nasty headache. No issues with dry mouth because I'm slightly nauseated, so hyper-salivating. Praying this works. Time for some melatonin and see if I can get some sleep."

For Weight Loss (Obesity/Overweight) "I started taking phentermine (Adipex P) on February 5, 2010, and as of today, I have lost 5 pounds. I am so excited to finally see something that can help me reach my weight loss goals. The only things that I do not like are not sleeping well at night and waking up at the crack of dawn, and the nausea. I am not a good water drinker, so having dry mouth encourages me to drink water to satisfy my thirst. My starting weight was 213, and I want to reach my goal of 145, which was my weight before all my children. I only exercise three days a week right now, and my eating could be better. So when I get completely on the right track with exercise and nutrition, I have faith that I will reach my goal by summer."

For Weight Loss (Obesity/Overweight) "Started phentermine 30 mg on 1/7/11, as of today, 2/12/11, I have lost 21 pounds. I lost 8 pounds in the first two days, I was so sick to my stomach. I never had a loss of appetite or increase in energy, just the dry mouth, which I still get today, but only right after taking the pill. I did read that you have to change your eating habits, so I decided on the first day to start calorie counting. I started with 1,800 calories and have decreased it by 50 each week. Now at 1,550 calories and still losing weight, although much slower now. Once I finish my second month, I will probably stop for about a week and then see if my doctor will prescribe for 2 more months. I would like to try the 37.5 next time though. We will see what he says. GOAL - 100 lbs!"

For Weight Loss (Obesity/Overweight) "I started the medication on 3/11/15 and weighed 263. I am 5'10. 37.5 mg, 1 tablet a day. I go to the gym and walk on the treadmill for an hour at an incline of 13, then 100 sit-ups and then go to the arm workouts. I am on a diet and only eat grilled fish, tuna, and fruits. It seems that I am only down 15 pounds. When I am at my desk during the day, I drink tons of water and have my weights, I continue to work on my arms. Just cannot believe that I am not losing more. I am hoping that I am gaining muscle and that is the difference. I was getting really sick to my stomach and cramps on the meds, so I stopped taking them for about 4 days until I realized I stopped eating when I took the pill. I was taking it on an empty stomach."

For Weight Loss (Obesity/Overweight) "33/F and 5'6", 332 lbs with high blood pressure. Taking Ziac 5 mg for HBP. Blood pressure has been under control for years, which is why the doctor gave the okay to take phentermine. Started 30 mg yesterday, 1/12, if the scale is right, down to 329 this morning!! Have dry mouth, nausea, and headache. Trouble sleeping last night as well. Still feel hungry, I think, but the nausea makes me not want to eat. Don't have tons of energy like others state. Wonder if I should be on the 37.5 mg instead. Will see what happens!"

I tried to sleep, but I can’t, and I feel frustrated because I have no energy at all. I feel sick, I feel like I need to throw up, and I think that my body is asking me for food, but I just can’t eat anything. I have 2 days that I haven’t slept at all. I feel like I’m doing drugs or something, and I’ve been taking these pills since 3 days ago."

I do not feel energy at all, in fact, since I didn't sleep, I didn't even want to get out of bed today. I've had a bad headache today and feel a bit nauseated too. I'm going to keep trying it, but just wanted to go over some side effects after my 1st day on it. I hope to lose weight though."

I exercise intensely 5 days a week and have been on a low-carb diet. While taking this drug, I have severe nausea and headaches. It’s to the point where I take headache medicine before I take the drug. My appetite has increased after taking this drug, it makes me feel like I’m starving. My first two days on this drug, I vomited. Hopefully, my body gets used to it, and the pounds start coming off as I go into the second week."

Today is March 24, 2017, and the first two days I took half, because my doctor told me to, just to see if it works. But I felt I didn't get a reaction, so as today being the 3rd day of me taking it, I took a whole pill, and immediately I started getting hot and sleepy. I felt nauseated until I threw up. Yes, the pill made me throw up. I have tried other weight loss pills and not worked. This pill is not cutting my appetite, but it is making me very thirsty. But it's only 3 days of taking the meds and 1 day of taking the whole tablet. I just hope it works..."
