By GI tube, do you mean an NG tube? They placed one in me during my surgery and took it out the next day. However, five days later I started vomiting and had to have one stuck down into my stomach again. It was not pleasant going down but boy did it ever relieve that nausea and I couldn't begin to tell you how much bile was brought up.
They had me walking the day after my surgery. It wasn't easy but I managed to walk halfway down the hall and back and every day thereafter I walked a little further. I had some complications while in the hospital and was in there for eleven days. I suppose I feel "normal"...lol but not like I would like to feel. I suppose I am so used to doing things that when I cannot do my heavy housework it bothers me.
