Adipex-P (phentermine) for Weight Loss: "My wife started taking Adipex in December of 2014, she finished it up through April 2015 and went from 187 lbs to 152 lbs. She kept to the same 1200 calorie diet she has always done for almost two years, and she works out on a variety of fitness classes to running an hour on a treadmill 3-4 times a week. It is 6/14/15 and I weigh 288 lbs and I am 5'10". I work out 4-5 times a week doing exercises like basketball twice a week for two hours and running two other times a week and lifting twice a week. So I am at the gym 5-6 times a week. Now that it is summer I plan on working out for an hour in the morning 3 times a week of cardio and lift at night."

For Obesity: "After experiencing extreme weight gain due to a horrible experience with an imbedded IUD, I was advised by a colleague to try adipex 37.5. I have been taking it since June 1, 2015 and started at 238.2 lbs. Today I weigh 227.4 lbs. it has helped me by suppressing my appetite, increasing my energy and giving me motivation by seeing my weight loss occur so quickly. I walk twice per day and lift weights three times per week. (Arms, legs, abs) I had the dry mouth but lots of water and Biotene help. Insomnia is managed by taking pill no later than 1pm. No rapid heart beat & managing salt intake may help BP. I stay below 1500 mls daily. Will update next month. I'm happy."

For Weight Loss: "I started taking the 37.5 MG dose 4 days ago. The first day I felt very strange.....heart racing, skin crawling, cotton mouth and such. Since then that has gone away. I have little appetite and have to remind myself to eat. I drink ample amounts of water. No soda or fast food. I have chosen to try this route instead of bariatric surgery. I suppose time will tell."

For Weight Loss: "Update! Tomorrow will be a month I've been taking Phentermine 30mg a day. The dry mouth went away. I am pretty much feeling normal. I started out at 178 and lost four pounds in the first week. However then it has slowed down to 1-2 a week and I'll lose it, gain it back, and lose it again. I eat something small for breakfast, usually skip lunch, and then eat supper. As of tonight I am 166. So 12 pounds in one month! I'm only prescribed this for three months so I'm hoping if I keep losing 1-2 a week I can be at about 150. I'm 5 3. (My prepregnancy weight from my 6 year old is 112 and I don't intend to get to that again) second child is 5 months old and before her I weighed 160."

For Weight Loss: "I started on phentermine 37.5mg almost 1 month ago. I was prescribed this in conjunction with another medication after visiting the doctor because I was experiencing constant unusual feelings of hunger. The doctor said he wanted to see me below 200 lbs - I started at 203 and now after one month with phentermine am at 198. I was excited to try it because I read all these reviews and since I already have a good diet and exercise 3 times a week, I thought I would really see some results. I had the feeling of adrenaline and rapid heart beat the first day only. Never kept me up at night. Dry mouth has been incredibly annoying, though it forces me to drink water...all the time. Been eating a whole lot less than before but not seeing major results"

For Weight Loss: "This is the 1st time I have taken Phent. Started 6 wks ago on 15 mg + w garcinia gambogia and I felt great and full of energy for 1st 2 wks. I am 5'2" and was at my highest weight 162 lbs. I have been going to the dr every 2 weeks and he also kept me on a diet. Low carbs, lots of veggies, fruit was ok. He has kept me on specified diet plans. No more soda, or juices, or sweets. At 6th week he increased my dose to 30mg am +15mg noon. My insomnia is bad and I'm more jittery. So I cut off lunch dose off until I feel better. I am now at 147. Not as much energy but not sleepy. Dr kept me on lower dose because I have meniere's disease and my migraines are bad. I haven't had any episodes of vertigos or migraines since on meds."

Adipex-P (phentermine) for Obesity: "I started phentermine on 5-26-2015. First day taking it, I got shaky, the chills, and my heart raced, but it will be 2 weeks tomorrow and those symptoms are no longer there. Unfortunately I don't get much energy as others described, but my appetite has decreased a lot and I get fuller easily. I've lost 15lbs so far, but I eat about 1300 to 1600 calories a day, and walk every day."

For Weight Loss: "Started phentermine 30 today (6/7). I have PCOS & on BP meds that keep BP in normal range (122/72) About 1 hour after taking phentermine, BP increased to approx 149/87. At 2 hours, almost back to normal. Slight headache.PCOS makes it difficult to lose weight. Trying this med to see if it will jump start loss- having 110lbs to lose & allow for more mobility to exercise. Will provide updates"

For Weight Loss: "This drug is amazing! I had my first baby and I gained so much weight, nothing was helping I tried every green tea there is and nothing helped I kept gaining weight! So I finally went to the doctor to see if there was something wrong with me and all my results came back normal. He then talked to me about a weight loss drug that's affective I said I would try it but I wasn't satisfied because I thought all these weigh loss medications are fake. I was 175lbs 5'0 I started adipex 37.5 on 5/17/15 and today 6/6/15 and I weight 159.9. That's 16 pounds in 3 weeks!!!!! I was amazed I was shedding off the weight so quick I couldn't believe the scale! I am so much happier and feel great my goal is to be back to my pre pregnancy weight 135!"

For Weight Loss: "I take 15mg phent. daily after breakfast, plus 25mg tenuate (3x day). Started 6 wks ago, lost 12 lbs in first 2 wks, my diet mostly veggies /chicken, some berries or watermelon for snacking. I walked for 15-20 min/ day. It diminished my appetite, easy to avoid sweets. Lost only 2lbs following 2 wks, and remained the same the following 2 wks. It affected my already poor sleep, & having more severe headaches, dry mouth & light sensitivity. I'm more tired, constant ringing in ears now; should I stop Tenuate & double dose of Fentermine only? Where's energy I should have? My Fibro knots in back/shoulders came back; discouraged. Need to get back with Doc for advice to continue weight loss."

For Obesity: "The first week I took this pill I lost an unexpected 15lbs! I was on it for 3 months. The amazing uplifting increase in energy and decrease in appetite was astonishing. I had to force myself to eat. I felt like super woman. I did learn that taking this pill too late has some horrible insomnia effects so take it ASAP. Downfall, after the first few months the "energy effect" wears off and the dramatic weight loss slows"

For Obesity: "2nd day on phentermine. So far I love it. I started exercising a few days before I got on the drug so I think that is helping as well but I have lost 5lbs in 3 days. I was 190 on June 1st and 184.6 this morning so will update in a month or so. I don't crave food at all and it is so nice to not be hungry 24/7. I'm not experiencing the dry mouth like some but I've also been drinking a ton of water. I did get a headache my first day though I think from not eating as much as I'm used to. Hopefully I can work the kinks out of my system! Thank you everyone for your reviews!!!"
