Madman, they havent started showing it yet. That wont start until next week.
Ozzy did a LOT of drugs. What really got to him was the fact that he was drinking 5 quarts of Vodka a day. He got so drunk once he lost his sight temporarily from what I hear. Tried to strangle his wife. HE was messed up on drugs for sure but even he will tell you that what really got him was alcohol. Huge amounts of Vodka or gin nearly killed him.
The guy has a talent for finding great guitar players though
