Follow-Up:
I have the same problem and it is scary. I was prescribed Clonazepam and it puts me right to sleep, but I don't want to have to always be on meds. My doctor believes I'm having the problem due to anxiety. During the day I have a real hard time swallowing food because I feel like I'm going to choke or I do choke. It's some sort of fear and any little sounds or the antisapation of a sound triggers it. I can't go out to eat at a restaurant anymore or movie theaters because I'll choke on my own saliva when I become panicky. I barely eat around my own family anymore. It sucks being like this.
