I had my op on the Monday, and the drain out on the wednesday afternoon. Was so relieved, as I'd managed to pop it open at one point. They had had to pin it to my pyjama top in the end.
Having that out, and not needing the flow pulse thingies on my legs, meant that finally I was able to go to the loo without having to call a nurse. I could still wheel my drip in with me.
I am really bad at having to depend on people, so it was a major relief.
