Sadly,
I wish I had some advice for you. I can never be reversed, since I do not have a large intestine or a rectum anymore. I'm okay with it and don't miss them, since they were badly diseased with Crohn's. I hope you have a good visit with your doctor on Wednesday and get some good answers to your questions.
StomaGrrrl, I'm glad your surgery was a success and that you were able to eat a real meal today. That must've tasted delicious!
