Random Nausea

There could be many reasons for nausea. I'm not a doctor and I don't play one on T.V but from my experience this is what I have learned: I always get nauseas after I work out, doesn't matter what I do before or during it always happens. I don't know if yours starts after you work out or not. Milk in combination with what your having for breakfast could be upsetting your stomach. Sometimes things just don't go well together. If you get over-hungry you can actually become nauseas. You said you haven't been eating a lot, and this could be kind of a vicious cycle. If you don't eat because you're feeling sick, the not eating could actually make you feel more sick. These are just a couple of ideas. I have had plenty of experience with nausea, having had stomach trouble as a kid. So I just kind of threw out some of the things that I know have triggered it for me in the past. Play around with what you're eating and see if that helps. If it doesn't go away with in a week or two, and you're really concerned about it, I would say seeing a doctor wouldn't hurt.

I don't know your gender, but will ask any way... Are you pregnant? The reason for my question is because many expectant mothers complain of sensitivity to milk. Allergies to certain things can pop up later in life even though you were fine with them before. About the water: Eat something first. Drinking anything on an empty stomach will make me sick too.
