When my post vaccine sensitive stomach issues exceed my abilty to tolerate or relieve the discomfort, I go on a food holiday. For my worst days I am just consumng distilled water, which I had to do for three consecutive days when my food sensitivities in a gluten-dairy free diet shut down my kidneys and worsened my chronic constipation. Both kidneys and liver were functional after the water fast. For moderate senstivities, I stop regular food (gluten-dairy free), simplify diet, Strangrly organic coconut and raw organic cashews worked as interim foods and lowered discomfort.
