I switch to cream of wheat every now and then. Like you said, oatmeal gets old after a while. To switch things up as far as oatmeal...pour out a serving of oats in a bowl, then get the low-sugar quaker oats packets and mix that in with the regular stuff. It adds a little taste without all of the sugar.
Speaking of Cream of Wheat...is Malt-O-Meal the same thing??? I use to eat that too...add some sugar and some butter, good stuff.
