if you guys are after an interesting read when it comes to life on the road as a wrestler check out Mick Foley's autobiography. It's called "Mankind: A Tale of Blood and Sweatsocks"
He basically touches on all the crap being tossed around in this thread. At one point he says, if a guy looks too good to be true, then he usually is doping. The guy also mentions that a lot of wrestlers out there are running around with twisted ankles, or torn ligaments, injuries that would put a mailman on his ass for a couple of weeks. Sprain your ankle one night, and you're out getting tossed around on the mat again the following night.
The wrestling business is so competitive. The lesser known "superstars" can't afford to get hurt. For every one that drops off TV, there's three waiting to take his place. So you jack steroids to get that physique that will put you on TV, you pop painkillers to deal with the bumps and bruises you get so you can keep your job, and you drink, snort lines, and abuse any other substance you can get your hands on to deal with the fact that you're on the road 300 days out of the year.
