That is soo common, i need two beers before stage to stop my hands shaking.. And i got 150+ gigs on my history.. Now that i’m behind stage &/ FOH, it’s the opposite, totally clear head before the show. Most bands i’ve played want to take that 2-3 beers and one during the show, just to calm nerves but not enough to dull senses. If you think the alternatives from big farma.. Two beers is way better for you. And that’s not a sign of alcoholism, continuing to drink is. And somehow she is way cooler now. Figure that out..
