OK, so my right eyelid started to twitch the last week of November. I wasn't getting a lot of sleep, I was drinking lots of coffee, and I was looking at a computer screen all day at work and then all night at home (that's why they call it homework).
I would be more worried, like, "quick, buy more life insurance", but Cathy assures me it isn't anything serious. She sounds confident, so either she knows something I don't, or she already bought that large life insurance policy on me and is just waiting for me to pop. :-p
Anyway, I did a little searching and really didn't find much. Perhaps the combination of stress, eye strain, coffee, sugar and lack of sleep is doing my eyelids in, I don't know. I've been getting more sleep, so I'll try cutting back on the caffeine. I guess I won't worry unless it persists or extends to other parts of my face. (eww)
