I grew up on Co Co Wheats. I too like it a little lumpy and have found that instead of adding all that sugar, that if I add French Vanilla coffee creamer it adds the right amount of sweetness/creaminess.
It is a northern cereal. I couldn't find any when I moved down here to NC back in 84 and had to bring it back with me when I went home to visit my parents.
Adding a touch of salt also gives it a nice flavor.
