I think he's just heavily into his booze and drugs. He's gone through stages since the HAND tour where he's been either boozed up or sober and it's always clear to see. At the moment he's been off the wagon for a long time and what's worrying is that he's surrounded by enablers. Half the people working on his tour looked out of it. In Bon Jovi he had a boss, now he doesn't. Lets hope his wake up call isn't an over dose or liver damage but with substance abusers going cold turkey is the last option.
