Creatine problems..

I have noticed that after I take creatine monohydrate I get nauseous. I am using Jarrow brand, this one http://www.vitacost.com/jarrow-formulas-creatine-monohydrate-600-g I am not loading just taking the maintenance dose of 6g. I take it after my workout and I am drinking 24 ounces of water with it. I am not getting muscle cramps or feeling dehydrated or anything. Just a really strong sick to my stomach feeling. I was wondering if this happens to anyone else??
