Several times lately As I am falling asleep I can t swallow and mouth is very dry. It feel I will choke to death.I get ice chips to add moisture to mouth. This is a scary paralyzingly feeling. It last an hour or two. I had a sleep test last week, a throat X-ray with barium today and will have a scope down throat next week. 2 of these occurrences were by taking a new pill after my normal meds. Once 1/2 tablet of Trazadone and another time I took 2 ibuprophen. I thought an allergy, but had a spell last Sunday nite with no extra meds. I had a stroke last summer. I am bipolar and take my reg meds each nite....no acid in throat feeling, just swallowing . Never know when this will reoccur.
