Hydrate....cold water naturally burns more calories

I'm struggling today.  I don't feel well at all and couldn't finish my first abs workout.  Hopefully, this oatmeal and huge cold bottle of water will help.  I drink about 4 Liters of water a day.  Yes, that's a ton of water, but it keeps me hydrated and helps to fill me up.
