I feel for all of you and hope for your healing.
A doctor in a hospital gave me a remedy that works very well.
It is called the BRAT DIET.
It stands for BANANAS, RICE, APPLE SAUCE AND TOAST.
Eating these things will stop diarrhea. .and vomiting.
Obviously you can not live off of these only, but if I feel the problem starting, I incorporate these with my regular food.
Just thought I would share.
