I have been off it for 6 weeks now. Good stuff. I never had bad skin but always had 1 or 2 zits. It dries the hell out of your skin while you are on it. My skin was so dry all over... esp my face. Mid-treatment, I had to stop using soap on my face b/c it would dry it out too much. I just used water.
My lips were, by far, the warst side effect. I had to use special chap stick 24/7. Literally, I had to reapply every 10 minutes. I would even have to wake up in the middle of the night to put more on. It was sick shit. Then, I developed a nasty cold sore that woudn't go the fuck away.
But, now, after all is said and done, it was all worth it. You have to see your Doc every 3-4 weeks and need a blood test every month, too. It prob cost about $5,000 for the treatment. But, insurance paid for mine.
