I have been noting several references to caffeine and dyskenesia recently and would like to offer my own experience. I went cold turkey off caffeine about three weeks ago (most of my intake was from hot and iced tea). In that time span i have had *no* dyskinesia, compared with my head/neck moving back and forth unless i focused on it and controlled it, and a somewhat jumpy left leg. Also (don't know if this is related) but i seem to have less stiffness in my legs. I am sleeping better recently too, since my body is less active (though we all know what late evening caffeine can do to anybody). Eliminating caffeine has been very helpful to me; since i rarely drink coffee or soda, it was a relatively painless seperation. I'd be interested to hear other people's experiences. Cheers, Jeffrey
