I was wondering, what should I eat during and before a big tournament? I've already learned that sugar is a no-go for me for the most part... Any advice? Thanks in advance, ~CSS

My question is different from Eating and drinking before and during a game.
I find that sugar affects me adversely, and all the answers on the other thread are referencing sugar... I need something substantial...

...what should I eat during and before a big tournament?

Try taking a look at an article that FM Mike Klein wrote for Chess Life, the USCF publication, in 2008. It's available here.

It recommends nutrition for before and during play, but it also emphasizes the importance of a good diet all the time.
