Yeah, I still get a bit of stage fright especially in a large room but, as you say, it pretty much goes away once I start "performing."

A shot or two of liquid courage doesn’t hurt either. Though beyond that you risk exceeding the Balmer peak.

I don't think I'm alone in finding it quite suspect if people walk around smelling of "liquid courage" in professional settings.

Don't drink coffee before going on stage. At least when you're old like me.

That's not what liquid courage means ;)

(Though that is otherwise good advice!)
