Ooh, ooh, ooh! I'll go first!
I find that if I don't have some protein with my carbs as soon as possible after I stop riding that I feel VERY tired and hungry all day. So, I make sure I have some protein - some PB&J on a bagel as soon as I can after my ride. Otherwise, look out - I'll eat everything in reach, because I'm too tired to move far from the couch!
