i just posted my experiences and saw your post.
i think that the breakout period is about 3 wks.
as it goes on, what i've observed is that what does break out isn't as severe as the first breakouts.
i do not go to the doctor or take any meds for my PI, and i really don't know of anybody that that route has helped any better than doctor time.
don't worry steve, this thing is going to go away...relax as much as you can.
