I've made my best gains when the only thing i changed was adding a huge PW meal consisting of a shake containing dextrose and/or honey, whey, and supplements, and a bowl of something relatively quick-digesting, like grits. Anyways, that's a good way to get the extra carbs....make a bowl of grits, add some dextrose. Pretty simple, really. You can buy a bag of dextrose at most health food stores for a few bucks.
