I don't eat a meal before a game. I especially avoid putting starchy food in my system before a tournament game. I know my metabolism enough that food in my stomach makes me sluggish for a couple of hours. Pasta makes me outright sleepy. Chess is different than cycling. I load up on pasta a day before I go on a bike tour covering more than 30 miles. I can take coffee before or during a game. I also take a Vitamin B supplement for every day of a long tournament.

Interesting.. perhaps some sugar could get you high before a game! But not too much, or you'll be too jumpy during the game and get yourself complained to an arbiter for distracting your opponent!
