I have a very annoying tic. It's annoying for me, and I'm sure people who would look at me for a long time would get annoyed too. It's on and off, but it has been rather on lately. I blink. My left eye "blinks hard", you could say, full with tension on the left side of my face.
That already was not fun, but now I'm getting an added side effect. When the tic kicks in and I do it a few times, I get the feeling that I'm about to throw up. I even get that throat movement whose English name I can't find. Not fun.
