I actually don't think the protein is the problem, it's iso mix and I never had problems with iso. You guys are probably right about the creatine though, I'm using a mono blend, guess I will back of the intake a little then get some cee once I run out.
Also, my sugar and salt intake is almost nothing. I'm drinking lots of water throughout the day and if its not water its a protein shake.
Oh, by the way, could you guys recommend a good cee blend?
