I have been taking
Phentermine on and off for a couple of years. Here is my personal experience. Start off on lowest dosage which I believe is 30 mg for a couple of reasons. One because it will be just as effective and you will experiance some hyperness and jitters at first anyway so that helps minimize that. Secondly, the drug looses its full effectiveness after a few weeks, so as you go along if you decide to continue you may want to move to a higher dosage to achieve same results. I haven't noticed any withdrawl symptoms and this may be because the drug does lose its zing after your body becomes used to it. If you notice this you can just continue, up dose or stop using it for a couple of weeks and then start again. I did notice when I took very high dose that I developed a rash on neck and face -- I think was too strong for my system. Just take one hour before or after breakfast and drink lots of water! Good luck!
