Then I would definitely drop this guy and never, ever use him again! I would save the "more cheat like" carbs; e.g., brownies, reeses's PB cups, candies, etc., for just before pump up and going on stage. Honey and rice, or rice cake with Honey and Peanut butter work real well for loading sources. Just have to be careful with the Honey...sometimes, early in the morning with that much sugar will spike your levels and take a little bit to compensate (since generally speaking, sugar is scarce during prep). For protein sources (with the carb) I usually like to stick to red meat, like Flank steak. That seems to work the best for me....but, that's during the day and not just before going on stage.
Will this be your only show this year?
