For Weight Loss: I've been on this pill starting my second month now. I lost 11 pounds in the first month without changing my eating habit a whole lot other than just drinking water and I haven't exercised like one needs to. This is my second month & I am changing everything. My fiance is also on the pill. He lost 18 pounds the first month. He drinks nothing but water & exercises daily plus eats healthier. The side effects were bad for both of us the first few days. But now we both only get dry mouth. It works! I would recommend to everyone!

Review by Alice Wonderland:

Adipex-P (phentermine) for Weight Loss: I've been on this medicine off and on for 6 months. I've lost about 30 pounds. My cycle is 1 month on and one month off. If you take it more than a month your body gets used to it. I have found giving the body a rest and allowing the metabolism to adjust without works best for long term weight loss and maintaining. I started at 180, currently at 150. I get bad side effects, but seeing the scale move and clothes fit motivates me to move on. If you exercise with this medicine it can make you nauseated and cause vomiting. Exercising first thing in the morning, then taking the medicine works best to prevent nausea and vomiting. Also, I find it important for users to change eating habits. Suggest clean eating 6 days on 1 day off.

For Weight Loss: I'm 24 years old, I have Hashimoto's (hypothyroid) and am 5'5. I weighed in at 217 lbs on March 25th which is the day I started the medication. It's been seven days and today I am weighing in at 204, 13 lb loss. I've been primarily juicing all three meals per day. I had a full meal one weekend night and have had healthy snacks here and there such as raw almonds and avocados. I've been drinking about 1 gallon of water per day. I just worked out for the first time on day 6 so we'll see how my second week goes now that I'm burning more calories. No negative side effects, dry mouth occurs but as previously stated by everyone it's just makes the water intake that much easier.

For Weight Loss: I started phentermine 3/1/14 it took about 3 days when I noticed my appetite went away. I was not exercising and when I ate I was still choosing the wrong foods, I lost weight, (like 1-2pounds), But when I decided to "get real" with myself ( excercising, elimination of sugar, flour, bread ) The weight came off. Start Weight 181 As of 3/30/14 lost 20 pounds 161!

For Obesity: I started taking Phentermine 37.5 on February 27, 2014 and so far I have lost 13 pounds. When I first started I was VERY jittery with huge pupils. Now that time has gone on, I am feeling much better. I do have horrible mood swings and can be fine one minute and snap on you the next. Other than that, I am very impressed with the weight loss. My Dr. did inform me that the second month I may not see as much change. I am determined to prove her wrong.

Adipex-P (phentermine) for Weight Loss: I started in Adipex Feb 16th. I weighed in at 308lbs, the heaviest I've ever been. As of March 27th I am now 260 lbs and going. I run 5 miles everyday and totally changed my life style. Drinking lots of water I probably go through a case and a half a week. I did experience the dry mouth and a serious boost of energy the first day I took it. After that it's just been dry mouth but hey I'm accustomed to drinking a ton of water. If you change your lifestyle and hit the gym it works.

For Weight Loss: I eat fairly healthy and exercise at least 3 times a week however my weight wasn't dropping so I went to my doctor. He prescribed phentermine 37.5 mg and I have been taking it every morning before breakfast. The only side effects I noticed was the dry mouth, but it just encouraged me to drink more water. Didn't have any problem sleeping, irritability or pounding heart like others have described. I go back to my doctor In 2 weeks for my 30 day review. I'm down from 206 to 195 so far.

For Weight Loss: I started phentermine two months ago (mid-Jan 2014) and I have lost 25 pounds (almost 26) so far. Working out is a challenge with my kids so I just try to walk whenever I can. I mostly monitor my caloric intake to make sure I eat enough to avoid my body's starvation defense mode, because that would defeat the purpose. I usually do the protein meal bars for lunch or breakfast shakes and then a sensible dinner. Only discomfort is the occasional constipation when I don't drink enough water. But usually the dry mouth is enough incentive to drink as much water as possible. Also I completely eliminated soda and other caffeine sources which I believe helps avoid the risk of heart palpitations.

For Weight Loss: I've been on phentermine 30mg for almost seven weeks now. My start day was 2/1/14 and I weighed 215lbs. My last weigh in was 3/15/14 (6 week mark) and I weighed 194lbs. That's 21 lbs in 6 weeks! I just weighed in this morning and I'm down to 191.5lbs. Hope to meet my goal of 190lbs by Saturday. I eat low carb (not induction low) and exercise 3-4 days a week. Next week I'll be starting my day with morning cardio sessions. No complaints as of now. I love this.

Adipex-P (phentermine) for Weight Loss: I lost five pounds in three weeks. I took the pill five days a week and took a break over the weekend. I definitely ate more when I did not take the pill. Overall, I have been eating healthy prior to taking the pill, but this has definitely helped me to avoid rush eating of sweets and other unhealthy things at times when I would be very hungry or stressed. The pill alone is not enough. Exercising on a regular basis makes a big difference. I'm looking to lose five more pounds by the end of this month.

For Weight Loss: I am taking phentermine 37.5, usually taking a full pill, but sometimes only taking half because of the way it makes me feel especially at night. I have a hard time sleeping and have my heart pounds. Hoping these side effects will go away but it has been a little less than a month and I still experience them. I have already lost 22 lbs and hoping to lose the rest in another 2 months because my doctor said I can only take it for 3 months...if I keep losing like I have the first month I will make it. I just wish I wasn't experiencing these side effects because sometimes they are really hard to deal with.

Adipex-P (phentermine) for Weight Loss: I love this pill I take a whole pill every morning. I have lots of energy! I started 3 days ago and I have lost 7 pounds since then. It curves my appetite all day until about 5:00pm then I normally eat a piece of grilled chicken and drink water! But I would definitely say that you need to work out along with it because I think that's how mine is dropping so fast! My doctor told me that if he doesn't think a patient is losing what they should, he stops prescribing it.

My goal is 150lbs for the summer.

For Weight Loss: I started phentermine on 3/1/14, my starting weight was 205lbs. I have been steadily going up due to medical issues. At first the side effects were foggy brain and the jitters. Shortly after the first week had to have my gallbladder out so had to stop. Started medicine again, with being on medicine for a total of two weeks I am now down to 193lbs, that is a loss of 12 pounds of just two weeks. Very excited and happy with so far.

For Weight Loss: I started taking phentermine on 3/1/2014, I weighed 179 pounds, after only 10 days, I've lost 9-10 pounds. Which I'm ecstatic about. I haven't had any of the side effects that I read about, other than the dry mouth, which is also great. I wonder if that means I'm not taking as high of a dose as I should be. I'm only 5 foot 2 inches. Within these 10 days, the first 7 days I lost my 9-10 pounds, nothing has changed since and I don't know why? My appetite had decreased and I work out 5 days a week for 1.5 hours..what's the deal? Does anyone know why I might already be at a plateau? I'm excited to have lost the 9-10 pounds, but I'm slowly getting discouraged again because more weight isn't falling off..... help.
