Thanks, Claire, for your optimism and those several suggestions but I need to be fair with you and give you something of the context of what I meant by "missions stint." My wife and I and three children did two terms under Eastern Mennonite Missions in Tanzania, the first for two years (87, 88) and the second for three years (96-99). It was during the former that I had a kind of epiphany, a sudden realization that I'd gone several months without tikking. Then, I was back at it, with no similar let up during the second term. You will likely admonish me for this, but I have little to no hope of ever "getting rid" of this tic. I have for the most part, learned to live with it and to stop demeaning myself because of it. I used to think I must have some undefined unresolved relational or moral issue that drives it along. Believe me, I have agonized, prayed, resolved, chewed gum, gone without sugar, coffee, etc., and worn trays--all to no avail. Changes in my diet or environment seem to make no difference. In common with other tikkers, I don't "tik" when sleeping, though I do a lot of twitching. Funny thing about which I am consistent: I NEVER have to tik when I'm in a reclining position, even when awake! Now go "chew" on that! (Forgive the pun!). --Arlin
