I felt that why after surgery as well. I also had surgery on the same day, but I was determine not to let the pain win...by Friday evening I drove to walmart....Saturday morning did 4 laps around the track at a good pace. The more u move the better u feel. I thought I had a problem with getting liquids down so I would take a few sips, maybe let water sit in my mouth and spit it out so that it wasn't as dry. But u will be okay..good luck
