Thanks for your help and explanations Kaypeeoh! I'm not sure anyone is ever an "expert" on anything, there is always more to learn! But your personal experience does help! I will try the potato idea right before class and see what happens.

The only reason I thought trying the potato 2-3 hours before class is because it is really hard to workout intensely if I have any food in my stomach. But if I eat it alone, without any protein or fat, it should digest rather quickly.

Thanks for your patience!
