I have H.pylori and I've been on antibiotics "Clarithromycin, Amoxicillin, Metronidazole" for 6 days now, I still feel sick : diarrhea, nausea, queasy and feel like I have to vomit. I feel like these antibiotics are hurting me as opposed to helping me. Is that normal? And what is the best diet for H. Pylori?
