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: "I'm 24 years old and was at 291.2 pounds... about 9 pounds away from 300 pounds!! I knew right then I had to make a change. A friend told me about phetermine and I wanted to try it. I saw a doctor and I was prescribed it 37.5mg. I was also on a 1200 calorie diet. I started in May 2015 and I checked in on June 2nd and LOST a total of 17.2lbs so far. I Love it. I now currently weigh 274. My goal weight is 160!....I walk 3 days a week about 2 or 3 miles a day and drink lots of water. This works and I've never felt better"

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!!!"

For Weight Loss: "I just started phentermine today. My whole life I've been skinny. I've had two kids and still managed to get down to a size 8. Long story short I was on pain killers for 5 years straight got taken off of them abruptly, had a seizure , got on suboxone for the withdrawal of pain killers now I am 5'4 240 pounds. I have everything I need done for gastric bypass surgery but I have to do 4 months of behavior therapy so I am trying the phentermine to see if I can lose weight and then maybe I won't have to get surgery. I got off the suboxone a year ago when I was 200 pounds and gained 40 more. I can't stand up for more than 15 minutes without severe blinding back pain. Long story longer I now have high blood pressure. 3 fractures in my back."

Adipex-P (phentermine) for Weight Loss: "I started taking Adipex 37.5 on May 29th, my first time taking this medication but I can't seem to lose any of my weight gained from my second pregnancy. I tried dieting, exercising and nothing happened. My current weight when I started was 248 and the first day taking this I felt like If I started moving I wouldn't be able to stop. The energy it provides was amazing. So far the only side effects I've had was dry mouth. Starting to get a little constipated but I knew that was a possibility so I'm prepared for it. I weighed myself today and I'm down to 241. I haven't changed my eating habits and I try to stay active for at least 30 minutes a day. I'm hoping to lose between 50-70lbs."

For Weight Loss: "I was on Phentermine 30 mg for about a month and then went back to my Dr to get a stronger dosage (37.5 mg). The 30 mg worked for about 2 weeks and then my weight kept fluctuating and it wasn't suppressing my appetite anymore. I originally lost 7 pounds the first two weeks and then gained it back and then dropped 4 pounds again. Hopefully the higher dosage gives me better and more consistent results. I also plan on "upping" my exercise routine to accelerate the results. I was working out already, but obviously I need more."

For Weight Loss: "Phentermine is the only pill that works for weight loss.. I first took it back in the 90's and I went from 251 to 143 yes over a 100 pound weight loss. At the time I saw a Dr. weekly and also got a B12 shot. I had to weigh in weekly so that kept me focused.. Sadly I didn't change my bad eating habits and by 2002 I was back at 211. June 2011 I was 273 pounds.So I jumped started with Phentermine again but this time I only took it for about a month and use it off and on. I changed my eating habits so that I hopefully keep the weight off. The Dr.I went to in 2011 James "Michael" Anchors.gives me Prozac as he says that it helps the drug to work better and last longer (PhenPro). I went from 273 to 173"

For Weight Loss: "I've been taking this medication for 3 days now. The first day was a bit of a challenge as I felt very hyper. My mouth is dry, but from reading the results I am not alone. I have noticed I eat less and not craving any junk food. My goal is to loose 15-20 lbs. I am 5ft and weigh 143 pound. I appreciate all the reviews. They were very helpful."

For Weight Loss: "I don't know what everyone is talking about. I have been taking this pill for two weeks and I haven't lost any weight whatsoever. I barely eat, so it did curb my appetite. I do a light workout because I have knee, back, and wrist problems. The only positive thing about this pill is that I no longer fall asleep on the couch. Two weeks ago I weighed 208 and today I still weigh 208."

For Obesity: "This is my second time on Phentermine. I took it about 14 years ago, at age 26. I was 280 and I lost 94lbs in 4.5 months. But, I only ate protein and vegetables and I walked/jogged at least one mile each day in addition to 45 mins of floor aerobics, 45 mins of step aerobics, and 30 mins of weight training exercises. I recently had reconstructive surgery on my ankle and I gained 60 lbs since August 2014. My exercise is extremely limited at this time. I am starting at 280 lbs. I will update soon."

For Weight Loss: "i started taking 30mg of phen on May 01, 2015. I started at 160 and as of today, May 29, I've lost 10lbs. It would have been more, but I was out of the country for two weeks and didn't always take my pill. But now back on track and feeling great!!! Going to start my exercise routine this weekend, I'm sure that's going to speed up my weight loss. I think I'll be asking my doc for 37.5 for the next month as I'm noticing just this week my appetite is slowly making itself known but not sure if that's because I'm expecting my monthly visitor. But as far assure effects, just dry mouth which is fine since constantly drinking water. I'll update my progress next Saturday after my doc visit. I do have to say my clothes are getting bigger and looser!"
