Three weeks ago for no apparent reason in the middle of eating I was suddenly struck with a fear of choking. I wasnt choking, I just suddenly got the feeling that what I had in my mouth was going tp choke me.
Since then its happened 3 or 4 times, all unprompted. Im just happily eating away and the feeling hits. I have to cut my food into miniscule sizes (like the size of a seed) and even then I feel like it might choke me.
It just happened again now - I suddenly froze with my mouth ful of food and although I had chewed it down to a pulp I was convinced I couldn't swallow it because it would get stuck so I had to spit it out.
Ive never choked before.
I have no food or eating issues.
Nothing triggered it the first time it happened 
I suppose you could say I'm prone to feeling anxious and on edge.
Has anyone had anything similar happen? Its really unscary and unpleasant!
