I have had issues with heartburn for years now, and it turns out that I have an excess amount of acid in my stomach and that my stomach is inflamed. I was prescribed 40mg
Omeprazole, but bought the 20mg Omeprazole over the counter and have been taking 2 each morning instead. It ha been 3 days (and three doses) and I have had EXTREME severe diarrhea. My stomach is nonstop gurgling, I can't keep anything down, and I am constantly in and out of the bathroom even throughout the night.
