Sudden Diarrhea After Treatment for H. Pylori and Giardia

Ok, here goes: I was being treated for h.pylori and giardia with amoxicillin and metrodinazole and was a week into support supplements Atrantil and Berberine after those when last Wednesday, I got a very sudden bout of diarrhea. Every day all morning and sometimes at other times. Everything I ate(even after I switched to BRAT diet) has turned to liquid. Now also two days into timidazole because my naturopath thinks maybe the giardia was résistent. But also wondering if it could be c diff? Don’t want and can’t afford to go to ER. Trying to stay hydrated with electrolytes and bone broth at least. Also just started taking high quality probiotic, colustrum, and glutamine. But getting weaker. I could get really detailed as to how things feel and look but will wait to see if anyone has anything to add… thanks!
