Just my 2 cents...100 g maltodextrin : 30 g whey (and 10g fructose sweetner) always seemed to work fine for me. Working out is usually the last the last thing I do before sleep and drinking this has helped me feel much better the following morning. When I cut the carb's down to say less 50g in the drink, I feel like warmed-over dog doo-doo. Weird, no?
