4.0L Coolant level

I've got an '01 WJ and noticed that the coolant level in the reservoir is slowly, but surley decreasing in level despite the engine being hot or cold (I already checked that to make sure.) I'm also blowing a small amount of white smoke out of the exhaust, and yes it has that sweet smell. Anyone have any idea what the problem may be?

I know what most of you are going to say and I'm praying it isn't the head gasket. Luckly the truck is under warranty with the dealer.

Thanks
