I find I don't get the dreaded head staggers or the tummy wobbles as bad by drinking the old black stuff.
I'm not a culty person, but I recognise the need for nourishment when on a 5 or 6 day session, when the craic is good, food (or rather the going out and eating of it), can be a real pain, and can take away from the serious business of playing music.
As the man said "There's both eatin' and drinkin' in it."
Us Paddys are a practical people.
