Well I think it's a bit of a double edge sword. On the one hand, you need to get rid of the h pylori overgrowth to feel better, but the meds can damage intestinal flora. My best advice would be to test and see if the h pylori overgrowth is still there. If it is, maybe you can go to an alternative medicine doc to help rid you of it naturally so that you don't do anymore damage to your gut. If it's gone, then I'm really not sure what would be causing you to have such nausea all the time. Quite a perplexing issue.
