There's something to be said for the lowering of inhibitions and a bit of relaxation on your instrument. Some of my best ideas have come out of being incoherant, but additionally I have vomited while playing and made a total mess of things. You can't have it both ways. Have fun and make an occasion of it with your mates. But if you have to open a bottle just about everytime you want to jam, practice or gig I'd suggest a visit to the doctor.

But from what you've outlined, I don't think you have anything to worry about. I do practice after I come in from my local pub on Friday. Plus has anyone played well when totally bollocked, even though they did not intend to get that way. All Rights Reserved.
