Thanks all. I am going to put the brakes on and wait for the symptoms to stop (hopefully in a few days).
I guess I will add things back one by one from there then, starting with the water kefir, and if that goes well finally with the ACV, and try to tease out what here is problematic. I have a feeling that each of these is irritating my gut tho (or that they are causing die off which is).
I also have an extremely strong symptom match with candida so I have moved forward under the assumption I have it, but I have never been tested so I suppose its possible I have parasites and/or SIBO too..?
