Beth, just a quick thought, but it may be something with the pherenic nerve
I think the swallowing maybe something else...meaning that nerves to the gag reflex seem to be messed up with TOSers. We chick a=on a swallow of just silivia, wrong way liquids go down, and food gets stick and chock...I am not sure the relationship, if it is fibrous bands, or adhisions, lazy nerve stimulation forgetting to do its job right or what... But it is grustrating to just be sitting and start to chock on just silivia even.

do you get hiccups too?
Hope it resloves or you figure it out. Why not call Dr T and ask the physiology that may be causing it.
