weight loss
"I just wanted to let everyone know that if you have been taking it for a while (a month or more), be careful about moving to quickly after being still for long periods of time or standing up to quickly. If you stand up to quick, sometimes your eyes will get tunnel vision and then start to go all black. I have been taking phentermine off and on for several years. I use it as necessary for a little while and then I get off. If you do not keep up with your diet you will gain the weight back plus some, maybe double. If used appropriately, it will work wonders and can help you reach your goals, but don%u2019t over do it.  Know your limit."
