obesity
"I started phen one week ago, after dieting and exercising for 11 weeks and only losing 10 pounds. I'm on 37.5 mg dose. I started phen  on May 14 at 179lbs. I'm down 5 pounds! I have exercised twice. I've have serious dry mouth, headaches for a week, but yesterday,  no headache.  Twice I've felt mild numbing in my face, and constipation. The following may be too much information - you are warned . I also started my period 4 days ago, experienced HEAVY bleeding, for the first 2 days, like having to change my pad every hour and a half because I bled through to my clothes. I'm not sure if it has anything to do with the medication,  but it's not normal for me. But it's not bad enough to make me stop taking it!"
