The orange juice idea is interesting. I have notice a spurt of energy after orange juice. But if it's just calories... why not eat pure sugar? I'm not kidding. What makes orange juice so special to work like that? It's natural?
I'm still interested in the carbs idea. The OJ idea is getting a little old. But that works. I wonder about it in the long term though. But carbs. I need dense carbs. Lots of carbs in less space. Is there something like carb concentrate? Distilled carbs?
