Match Preparation - What do YOU do?

I'm not a competitive player, but I do follow some of the competitions and players. I have a question for some of the more experienced competitive players...

On the day of a match, what sort of preparation do you do both as an individual and as teams? For example:

Any team meetings regarding strategies or discussion of your opponents?
How much do you play/warm up? All day? None at all until right before match?
Do you have any superstitious rituals or specific things you do before matches?
Do you drink any alcohol to relax nerves (if of legal age of course)?
Anything else you do to prepare?

Hope to see good feedback on this... I think many would be interested.
