Maybe just reading the news is stressful!

I had good results with Zantac, years ago when I had similar symptoms. I think it's even available over the counter now. No troublesome side effects that I remember, except that I felt better after taking it. It's different than an antacid -- I think a good Dr. should be able to explain in layman's terms the difference -- so that if you decide to take medicine that you're comfortable with it.

Good luck, hope you figure out what's going on!
