Sounds to me it's a liver/bile issue that's just starting. I experienced the same things as heavyhitter. I'd get nauseous and I'd have to vomit, and only bile would pour out. After 5-6 times, it would finally calm down, and I'd be okay for a while. Later I had tests done, and my gallbladder was functioning sporadically so they removed it. Solved a lot of issues, but not before causing a couple others like having allergic reactions in my esophagus which caused food to stop there. Still sorting that one out. I'd definitely go get checked out by a doctor if I were you.
