Hi, I'm 27 and had a few zits here and there since highschool. When I turned 25 they started getting really bad on my cheeks within a matter of weeks. I tried antibiotics, first then that failed completely. Then this last fall it got so bad I wouldn't leave the house. And I am now all scarred from it. I was very depressed and decided to take a chance. My depression is gone now since I have started my course. I am currently starting my 4th month on 40 mg, considering I'm only 97lbs. All is well but I have severe back pain. Can hardly roll over in bed.
