I think that most people can generally consume moderate amounts of painkillers, steroids, booze, and even certain “recreational” drugs each by themselves.
Any of those in excess will cause problems.
Start mixing any and/or all of them, and your fvcked in a not-so-nice way.
The 80’s roster was notorious for both excessive and combined consumption.
Jake – to me – is the most amazing example for not only the copious amounts of shit he’s taken, but also for the fact that he is still alive!
Bulldog – painkiller OD, but he’d done his share of plenty of other substances over the years including cocaine and roids.
Dynamite outlined his own daily ritual, which included:
Speed to wake up in the morning and catch a flight,
Valium to sleep on the flight,
Steroids before training and working,
Painkillers, booze, and cocaine after the match,
Valium to get to sleep
He also claims that most of the roster followed a pretty similar schedule.
