from my past experiences its very hard to time everything for that little slot your on stage,,, youl be coverd head to foot in veins one minute then the next theyl all be gone
ive tried the lot, whiskey back stage one year, apple pie fillings, dark chocolate, wine vit c and glycerol etc etc,,,
did nothing at all last time out and ended up looking my best ever. I never carbed up that year either, kept everything the same, including my gear and just cruised in, and knew exactly how id look, with out last min magic theories
