"Prevention: Drink a couple of pints of water over the hour before showtime."
Don't know if she still does, but Peggy Seeger used to drink pints of water whenever she and Ewan took the whole evening at the Singers Club, she wouldn't drink anything else.
I remember one night when she was sitting on the stage during the half-time break, clutching her three-quarters full pint glass, a regular, somewhat tipsy, reeled up to her and said, "Can I top up your gin and tonic before you re-start, Peggy?"
