I had the same thing a month or so ago; it lasted for well over a month, on and off.

My BF had it, as did a woman in my office, and we all got it around the same time. Apparently that stupid, annoying, distracting eye twitch can be caused by allergies. Try some Claritin or something for a few days and see if it clears up. I know it sounds crazy, but once hay fever season calmed down, my eye twitch went away, as did my BF’s, and that of the lady I work with.
