Not Worth Risking Your Health
If there is one diet pill that is very popular in the market, that would be phentermine. Although phentermine is effective, it only works for short periods of time only. And it is also proven to cause side-effects such as severe headaches, confusion, depression and insomnia, thus I suggest that you first consult your doctor before taking phentermine, as losing weight may seem appealing, it is not worth risking your health.
