Twitches

OK so no pictures yet. I've been so insanely busy recently that some days I just cry because I'm so tired at the end of the day!

That being said, my left eye has been twitching since last Tuesday, and it's weirding me out. It's only a minor twitch, but strange nonetheless. Anybody had this problem before? Interestingly enough, it ceased twitching on Saturday and Sunday.... I wonder what the trigger could be???
