Fasting responsibly with plenty of water has been used for thousands of years as a healing mechanism or reset for gastrointestinal issues. Perhaps a hard reset may help and then slowly reintroducing things like organic bone broth and working towards nutrient rich whole foods and vegetables, with lots of water and good sleep.

I am rooting for you. Sending good thoughts your way.
