IMO drinking anything caloric during the workout is not good. Infact, you shouldn't eat anything within an hour of your workout, excepts I do take some BCAA's with Crystal Lite right before I leave and then drink a few liters of water during WO. Caloric foods/drinks during WO messes with your insulin at the wrong time, you're supposed to shuttle the nutrients after the workout AFTER you have just stimulated your muscles using water and blood to pump the muscles and replenish water loss during WO.
