I drink cow milk. Primarily 0%, secondarily 2%. Occasionally 1% or whole milk, too, and while in Europe primarily 1.5% but occasionally 0.5%. I don't put it in cereal as I prefer dry cereal, but often drink it alongside cereal.
I drink it most days, often but not always more than once per day. I'd drink it more except I tend to run out and not get to the store to buy more for a few days. Yesterday I had it with lunch, today I had it with dinner after buying some more on the way home from work. I'll have it with any meal (breakfast, lunch, dinner) or with a snack, but rarely have it on its own just because I'm thirsty. Then I tend to prefer water, juice, or tea (in order). I also drink it with fish, which some people find odd for reasons I don't understand.
