Is it ok to break open creatine capsules?

I've read a few blogs on fitness web sites but the only answer that is being provided is to buy powder instead. So next time I'll buy powder. As of right now I have a bottle of creatine capsules and swallowing 6 pills every four hours is kind of ridiculous. Does anyone know if its all right to break those baby's open and mix them with water? I can't see it being much different then swallowing them with water, but I wasn't sure if there was any risk of "over dosing" on the powder in creatine capsules or not...?
