i was jus wonderin if anyone else has noticed any side effects such as frequent impotence, or decreased sexual desire? I really think it has sumthing to do with the phentermine, bcuz i have never had this problem before, and i have been on the phentermine for 4 months, and it has been occuring alot. Any help would be great on whether there is sumthing else to take to reverse these side effects, or anything like that. Thanks in advance.
