Oh that sounds great. Incidentally, my daughter's surgery was yesterday and she has a temporary ileostomy. They are hoping that resting the colon and switching to a new med will avoid making this permanent but the likelihood is it will be.
Just a little warning to file away. People with ileoostomies have a harder time staying hydrated so if you do end up getting the temporary diversion and hydration has been an issue you are going to have a bigger battle on your hands but you seem super motivated and seem to understand your body so I am sure you will do what needs to be done. They will also teach you all the tips and tricks.
