This happened to me about a year ago, for a period of a few months. I don't have a good answer for the solution but I do remember thinking it would never go away because I was very self-aware of it, if you know what I mean. I also remember thinking it was related to changing my breakfast habits at the time (I started to skip breakfast for a while), though I'm not sure if my reasoning was correct.
Changing the way or things I eat didn't help, although I did get back on eating on a proper schedule.
I also believed it would never stop because I thought my body would get used to repeating the same reflex/movement so often.
I don't remember when it exactly it stopped after those few months - which says something about the solution: it stopped around the time I started to really ignore it.
I hope this helps.
