It's cleaning out your system! The all oats one give me gas too. I like the brand flakes with blueberry the best. My snacks consist of yogurt, almonds, beef jerky, kashi granola bars, wheat thins reduced fat crackers with cheese, and a lot of fruit.
I like oatmeal in the morning as well, all of the oat products turn me into a methane machine. Great snacks, I also like Clif bars.
