I used to try to do it twice a year, but I've slowed down a lot since I turned 50.
I think my last time might have been last year...or was it the year before?
As far as a nice lil tipsy buzz goes, I might do that 3-4 times a year these days. When I was helping to run that open mic, it used to be a weekly thing, cuz that's how I was paid, & I deserved it, dammit.
I've never missed a day's work over a buzz, though, & it only affected me on stage twice, to my recollection...both times at an open mic, NEVER at a paying gig.
SMILE - it's the safest way to spread your cheeks!
