Yeah I'm a little newer to gigging so I still get a little bit of the butterflys, just a little. When I practice on the weekends I always seem to be drinking a beer or having a puff since I am not at work and relaxing with the band practicing. I have a decent tolerance so a couple before and during aint going to hurt anything. It just loosens me up and relaxes me, and I always practice that way but I am never drunk or sloppy just a little to take the edge off. I always drink a ton of water so I remain mostly sober anyway.
. I just don't feel it's worth the risk, that and my fingers slow down so much after the 3rd beer it's not even enjoyable to play, well I wouldn't go that far haha.
