Thanks. It sucks that we just have to medicate ourselves and hope for the best. Since my skin is clearing up, I know it's doing something, but to what degree I don't know. I have no idea how long to take it, if any of the side effects like the head pain is dangerous or not. Sometimes when I can feel the medicine in my system I get scared to go to sleep. My imagination gets the best of me, I think.
I agree, that it must not be profitable. There would be tons of experts if it were.
