Although I am a nurse, this is a post as a friend of someone who took
Phentermine (not as professional advice).
There are MANY side effects/ill effects associated with Phentermine, and it is still a contoversial medication in the medical field. If you are taking it, get as much information as you can about the drug because it is not without significant risk. I am not saying that you will (some people do fine, my friend did), but you should be very informed about that medication. My friend made the decision to take it, but I declined. Good luck!
