What did you guys eat on the morning of the SAT?

The last time I took the SAT (In Nov) I had a bagel and something small before the SAT, but I thought it made me more lethargic. This time I only had an apple and a Redbull on the way there. I felt much more alert and think I did much better. This seems to be contrary to what I was told my teachers, what do you guys think?
