i've found in the past that this is a symptom of poor quality creatine. Having said that, creapure is usually good to go, so that shouldn't be the issue.
I would be interested in knowing what that serving size is that you are taking?
Also,did you start or change any supplements around that time? I've had certain brands of whey not sit right with me.
