I've had twitches in both eyes before back when I was in school most likely brought about by stress and lack of sleep. Always went away after a good night's sleep, or after the test or project I was studying for / working on passed. Now-a-days I get plenty of sleep and my life is pretty stress-free, but I've developed this damn twitch in my left eye (my dominant / shooting eye) that's lasted about 3 weeks. Doesn't happen while I'm shooting, only other times of the day. I've been shooting about 5 things per week the past 3 weeks. I've only got 3 things next week and then 4 days off before 3 days all-day of track and field. I really hope it goes away. It's the corner of my lower eyelid. Maybe my sister-in-law can hook me up with a botox injection lulz (it's supposed to help... she works at a plastic / cosmetic surgery center) (also note I'm partially kidding, this would be a last resort).
