Vegan guidlines, what can I or can't I eat?

I've been vegan for the past 6 days and it's been weird. I don't really like and I don't like Veggies unless if it's served with butter. I like fruits, don't like tofu, dies it matter if I get it organic? Should I keep on the diet for football, I'm only doing it right now to lose some fat. I got a little slower, I just need to get a little slimmer. Can you eat seafood?
