what kind of carbs?
Wouldn't they be complex from the oatmeal.
I just use a cup of reg old fashioned oats with 1 cup water, 6 packs of splenda, a dash of cinnamon and 2 scoops of protein. (1 scoop Muscle Milk, 1 scoop of whey) and a little coffee if it's to dry. Allot cheaper than the "protein oatmeal" and probably a better nutritional profile too. Just mix it in a plastic, covered bowl before leaving the house and add a cup of water before 2.5 min in the microwave.
