Phentermine - How long does the side effects last? like the bad taste and the weakness?

Hello, I have been taking Phentermine for a couple weeks now and actually the only side effects I experienced was the dry mouth and bad taste but it only lasted within the first week, and nothing thereafter. It actually gives me a lot of energy and puts me in a great mood! But keep in mind that everyones body is different, but I know many people who has received my same results! Hope this helps
