Water Weight

I recently started taking 5g of Creatine to help with a few different things. I've also 'gained' bout 5lbs in 3 days! I know that's a "side affect" of the Creatine, but will it eventually go away? I know it's from my muscles holding onto water. I've been drinking about 90 oz of water each day. I've noticed since starting the Creatine that i'm not peeing like a race horse like i use to when i drank this much water.

Anyone else around here taking Creatine?
