I usually have a glass of squash or Coke. Squash is more frequent lately though. Tea is nice too, but I usually forget about it until it's cold.

Out of all the times I used to drink strong amounts of caffeine, I not once noticed that my reactions were any better. If anything, I was more awake and hyper, and more likely to make a mistake because I'm pumped up.

For some reason, my game seems to be improved when I'm slightly tipsy. Just relaxed and tipsy. I don't enjoy the feeling of being drunk, and it's quite rare when I do drink, but a cold bottle of Busweiser is my favourite gaming alcohol drink.
