dontscopeme,
I am so sorry you are going through all of this.
You may well have a mesalamine intolerance.
What about going on bowel rest for a few days?
Bread is not a good choice of foods, it provides little nutrition, and could be causing major problems if you are one of us who reacts to gluten and wheat.
I would suggest liquid diet, made up of chicken broths and plenty of water, for a bit - to give your gut a rest.
And of course, get in to see your doc to see what's going on.
Hope you feel better soon.
