I guess you have no choice but to dust off and go on with it. I've rarely been one who can order something with bread and toss it easily. Evidently, your resistance is low after exercise, so you'll learn to prepare for next time. You can do it!

I'm sure someone in the exercise forums can give you the info you're looking for about the timing of carbs and exercise. Personally, I find I have MORE endurance if I eat a protein/fat snack before working out.
