helicobacter pylori infection
"Taking it together with tetracycline, pantoprazole (a PPI), and 30ml of pepto.  Taking it all 4x daily for 2 weeks for a confirmed H. pylori infection.

Since I started taking it, I experienced mild to severe nausea and bloating.  Occasional cramps, as well.  The metro tastes absolutely awful, and swallowing it right away usually resulted in the pill getting stuck in my throat and dissolving there.  I found that taking it with grape gatorade and letting it sit in the back of my mouth for a few seconds made the experience less awful, but nothing can get rid of the aftertaste.

At the time of writing, I still have 5 days left of treatment.  I read on multiple review sites that despite the side effects and taste, treatment generally works."
