Naw! I don't do that. I fall asleep while playing music instead. In my drinking days I had beer stains inside my guitar. Now it's drool stains. Banjo's even worse. The drool just runs down the head and pools up around the bracket hoop. Dobro's worst of all 'cause you're already sorta leanin' forward to play it anyway. As soon as you start noddin' it's somersault time.   

You know, maybe that's why brass instruments have spit valves! So old farts who fall asleep while waiting for their turn to play can dump the drool out.
