Well, if it would all be just rational, things would be easy. Whenever I get off the track and eat carbs later in the day or miss breakfast (like last Friday), I get into carb cravings or sugar coma and lose control.. that's why I try to keep my carb intake as low as possible, without losing too much glycogen.
With my new training that's a bit difficult I found out when I was through my glycogen halfway the workout.. my whey-drink with fast-acting carbs saved me from bonking.
