I have been on phentermine for over a year now....in cycles. I have lost about 60 pounds! I cycle on and off to not het addicted, as it is very easy to like this drug. Allof the side efects listed in the above posting were noticed by me, however most went away after about 2 months, except the getting hot flashes and dry mouth. That I still get. I would not advise buying this drug off the internet, too many scams...I fell for them too. Plus your dr. can only write your prescription by law for 30 days at a time and only if you loose atleast one pound a month. At least that is the way it is with MS an TN. Oh, and if you use a FNP instead of a dr. they can only write the script twice a year each. You should remember Phentermine is not FDA approved, but the only truly legal and safe way to get it is from a pharmacy. Also know this - it is highly addictive. I love this medicine because it gives me a lot of energy and everthing just seems so happy while taking it. Who wouldnt get addicted to that? I would like to mentin that after a while I noticed hair falling out, acne, among other symptoms. When I consulted my DR, he advised to take 2 prenatal vitamins a day, one in the a.m. and one in the p.m., that took a while to work but about 2 weeks later i started noticing the difference. I askjed why prenatals? He said it has all of what my body will need - in comparison, its like being pregnant, something is sucking all the fat and nutrients i was putting in,and since I was never hungry, it all made sense. I know this was lengthy, but I hope it helps.
