Oh my, so sorry to hear that you are not feeling well. I have never been on bowel rest, but I think others have. I can't imagine that water would be bad for you, but definately check with your doc. You may also want to check if you can chew gum. Just to have the feeling of actually getting to chew something and to have a taste in your mouth. Hang in there, get plenty of rest and I will be thinking about you and praying for your fast recovery.
