Several people in my band swear by Bach's Rescue Remedy - you see them all knocking it back in the corridor while we are waiting to go on stage. It is basically herbal extracts in a brandy base (but you only use a drop under your tongue). It is available from health food shops and is designed to calm people who are having a panic. It's one of those things for which there is absolutely no scientific proof at all, but lots of people I know can't go on stage without it!
Is there a rule in contesting about performance enhancing drugs? I know the tonic that is recommended above would probably be legal, I just wondered that's all. :roll:
