Hi Kelly.
I am always aware of when it's time to swallow and get myself in position for it. I've choked to many times, not to be careful.
I've noticed that I have to sit straight and looking forward and maybe lower my had a little. If I turn my head to the left or right and swallow, I'll choke, every time.
It's not something that is a constant problem, but MS has made me constantly aware.
