I remember back in the 90's I was working 50-60 hours per week at my real job, practicing one night, then gigging up to four nights a week. With LA traffic, I was in the car up to four hours a day. I was so sleep deprived that I started using my resources... I had a tall stack (GB 410XB, GB 15XB, SVT) that was the perfect height. When the club was filled with a bunch of old, disinterested farts, I'd put the headstock on top of the cabs, lean against the cabs, lock my knees, and fall a sleep while playing! Yep, we were so tight that I could literally fall asleep and play. It was hard to pull off on a well lit stage or when playing tougher stuff, or during five part harmonies, but when I was stuck in a back corner, zzzzzzzzzzzzzzz... My drummer would catch me and throw a 5b at me. Not the best way to perform, huh?
