Drinking excessive amounts of water can be fatal - it causes cerebral oedema which turns a hangover into a funeral. Yes keep hydrated but "as much water... as poss" - don't be stupid.
Don't attempt to cook anything while drunk.
Especially chips.
Drunk cooking is at least as dangerous as drunk driving.
