acne
"I have had moderate acne since I was 16 (now 23) and I have tried just about everything I can think of and I was finally put on doxycycline 100mg to take once a day for 3 months. Although I experienced headaches and nausea in the first week, it has since stopped and I feel no side effects (so stick it out for at least a week to see if they stop). I am now in the middle of the second month and although my acne has diminished a little bit, I am still getting some new pimples pop up (smaller than usual which is good), but my skin has not completely cleared. I am also on this medication for extremely bad ingrown hairs in the groin area and although the medication is helping, it hasn't stopped those either. It definitely helped though."
