There are various things that might cause twitching--exhaustion, stress, magnesium deficiency, dehydration--but it started very suddenly last week, with no obvious trigger. I'm just lucky I guess.
Anyone got any awesome folk remedies? My friend's dad suggested tonic water for the quinine (about this same time last year, actually) but I just can't bring myself to drink enough of that for it to make any difference. Maybe it's just a summer solstice thing.
