"I started on this medication (37.5 mg) on March 12, 2015 weighing 217. Today, August 30, 2015 I weigh 175. In a few weeks I will begin a much lower dose. There are some negative side effects, dry mouth and constipation being the most annoying but I had no jitters or changes in sleep. I'm 47 and am 5'5 with a goal weight of 140."

"I've been taking this for a couple of months and have only lost about 4 lbs. I'm not hungry and am pretty good at watching what I eat, making healthy choices. I haven't been doing any formal type of exercise although I am busy everyday, working around the house and in the yard. I can't understand why I am not losing the amount of weight the other people are stating. Anyone have any thoughts or suggestions? I take one pill in the morning and 1/2 pill in the afternoon."

"I was on Phentermine. I lost 8 pounds because I also take Effexor, Topamax and Clonidine for other symptoms. My insurance company considered this a trial. I, after three months, was no longer covered for the drug because I couldn't lose ten pounds because of my other conditions. I now am going through horrific withdrawals. I cannot sleep nor eat properly. I have to constantly drink something to produce saliva. I shake constantly and have nightmares from this medication. If you are on this medication, DO NOT STOP TAKING IT!!! I learned the extremely hard way that this medication IS addictive! My doctor told me the psychiatric effects are my mental illness NOT the medication! So, I advise anyone, do not take this with psychiatric meds!"

"I'm 5'10" 54 year old female. I started taking 37.5 mg with 10 mg fluoxetine (Prozac to ease neg side effects) in the mornings one week ago at 203 lbs. I am already down to 191, a loss of 12 pounds in the first week. I've had no hunger and absolutely no cravings. I have been able to eliminate all sugars, simple carbohydrates etc. While I recognize that most of this is probably water weight, that has to go first! I have not started exercising but will do so this week hoping to maintain the momentum. Very pleased but need to continue to be disciplined as this is only a tool, I've got to do the hard work too."

"Hello I'm 5'0 was 146 when I started the pill, 5 days after being on the medication I felt the right side of my face feel really weird and very dry mouth. Didn't pay much attention to it on the 7th day I noticed I had developed Bell's palsy went to the ER as my MD believed it was the progression of a stroke. They did a CT scan everything was normal when I asked my MD if it could have been from the phen he said that's not a side affect he prescribes the medication all the time and has not had any complications but to stop the medication. When I asked the ER Dr she had no clue what phentermine was. I was really disappointed to have to stop the med as I had lost 6 pounds in 1 week. Wondering if anyone has experienced this symptom"

Adipex-P (phentermine): "Not obese but med change & back surgery resulted in an extra 20 lbs not normal for me. Doc required tracking of diet & exercise before RX was given and would only write for brand name as generic ramped up potential side effects. Continued regular monitoring & input on necessary long-term diet changes. I lost 30 lbs & have been off for a week. I eat foods I love & that are healthy so no sacrifice there. The energy it provided allowed me to create an AM yoga routine each day. Side effects of dry mouth & less sleep were there but minimal. Pretty tired in the beginning of coming off them but adjusting now. The goals we set together were met & the purpose of a lifestyle change/improvement were accomplished. This is a solution to changing your lifestyle."

"I started the pills August 20th. I haven't been to the gym yet, but I eat SUPER healthy now and a lot less than I used to; and I have lost 8 pounds within 5 days!!! It's so crazy. I barely am ever hungry and I get so full so fast. I do have dry mouth, but I drink a lot of water for it. My doctor said by eating good and exercise here and there I could loose up to 20 pounds in one month. Hopefully I'll be able to loose another 50 pounds by the next 3 months!"

"I have lost 80 lbs using phentermine for almost 10 months. it has been a great thing for me. I have energy to workout and have had no desire for soda in almost a year. I take it every other month and it is still working for me. I have a few friends of mine that are taking it as well and it has worked for them as well."

"I started on 8/8/15 at 257lbs, tomorrow will be 2 weeks I have been on it and I'm down to 240lbs, that's down 17lbs!! I work out 4 to 5 times a week, walking 3 miles or the elliptical for 45 mins. I have cut out all sweets as I noticed foods with a lot of sugar make me shaking while one the pills. I have like no appetite, but make myself eat at least 3 times a day, I mostly eat fruits and veggies when I do eat. I drink about 8 bottles of water a day due to dry mouth and excessive sweating when working out. I have only found 2 side effects dry mouth and constipation which I take a stool softener every morning to help with."

"I'm on day 6 of phentermine, only taking half of the 37.5 and start my whole pill tomorrow. So far so good, I don't have a ton of energy but I'm having to force myself to eat because I have no interest in food (which is really new for me). I am down 6 lbs in 6 days and am yet to hit the gym, I am following a low cal diet from my nutritionist. The only down fall is I have a really hard time getting to sleep, BUT I wake up feeling like I got a ton of sleep so either way."

"This medication made me go from 210 pounds to 150 and all I did was take it.....I hate to say it but I was lazy with his medication, i didn't even work out or wat healthy. However, without even doing so, I managed to loose weight and keep a good amount off. Granted, i wasn't very hungry while on this medication as it makes you lose your hunger drive, but i started noticing changes within the first week. By the first month I had already lost 15-20 pounds and maybe 10 each month after that as it began to get harder, because I had less weight to lose."

"I started on phentermine 37.5 august 6th it's been 13 days, side affects constipation dry mouth. I have dry mouth any ways due to other medications. At first I had energy but it's decreased not sure if it's the heat. I eat 1300 calories a day a drink loads of water mostly plain ice tea. So far about 8 pounds loss. Started weight 217 now 208 . I usually walk 2 miles but due to the heat I can't, I was hoping for a bigger loss but I have constant back pain, which doesn't help having Cage in my back. But I keep trying everyday. I'm not giving up!!!! It's a start :) my goal is 150..."

"I started phentermine 30mg on 8-4-15. So far I have gone from 129 to 120. I'm loving how fast the weight is coming off, but I don't really have any increased energy I was hoping to have. However, the weight is coming off and my appetite is suppressed so I guess it's doing its job. Hoping for the next 51 pounds to come off just as fast!"

"I started Phen. About theee weeks ago. Starting weight was 186lbs and im 5"6. Currently im weighing 171lbs. I love my results!! I can see a difference in my clothes already. Im not exercising yet, but i plan to start . Dry mouth is the only con. I also realized in week one that when i took a whole pill in the morning I found myself very hungry in the evening right before bedtime. The trick i learned was to take a half pill with breakfast and another half with a early lunch to keep my appetite surpressed all day."
