Have you gotten this checked out yet? It could be a sign of something serious. A friend of mine had an eye that kept twitching for an extended amount of time and found out he'd had a small stroke. Not the only thing that can cause persistant muscle twitches but it's worth getting checked out, if for no other reason than to see if the twitching can be relieved.
Nope, I doubt this is anything serious, but thank you for reminding me to be aware.
I sure hope that bug leaves your house soon. BLECH! It sounds awful!
