Can't sleep so I'm looking up some more stuff regarding caffeine. One of the studies that I read about regarding the caffeine/creatine mix said that caffeine could hinder the effects of creatine. They gave the subjects 5mg of caffeine per kg of body weight...that is a LOT. And another study said that caffeine hindered the effects of creatine, but that the muscles still absorbed creatine from the blood just as well. wtf? Decide for yourself...
