I choke on liquids quite frequently. When I had my Thymectomy they messed up my vocal cords so they don't close all the way which makes the choking worse. There have been times when I have taken a big swallow of something and I know it isn't going down. I wind up spitting it back all over myself. Then start the convulsions, eye watering, hacking up a lung and my personal favorite loss of bladder control while trying to get the liquid out of my airway. I try to see it with humor although there have been some very embarrassing episodes.
