Eat something! And not something weird!

I cant say what will soothe your stomach. I tend to chicken noodle (or rice) soup.

I have taken excedrin or ibuprophen over a week or so because of muscle or headaches, so not exactly an overdose, but for longer than the recommended period. I think it just irritates your stomach lining. I dont think you immediately get a hole in your stomach from it. And you do drink a lot of liquid, so unless you take the pills dry.
