HitchhikinProhibited: Same thing happened to me a while back.Turned out to be jet lag and too much coffee.I thought I was getting Parkinson's.So think about stimulants(coffee, caffeinated sodas,prescriptions), stress(boa constrictor in bathtub), fatigue (physical, mental, like riding your bike a lot worrying about final exams),diet (not enough B vitamins),hangovers- and if it's still there in two weeks,see your doctor
