Thanks, I get the point from Diva about needing a bit but treewind has my symptoms and its stopping me progressing. Will I ever?

I used to find with snooker that zero beer was not much good, 1 pint was better, 2 maybe and downhill after that. Does a similar curve exist for tunes?

Eyes shut or open. I did find that total concentration on the tune in my head helped, obvious I suppose?
