A few months ago I happened to get one of those rubber wristbands (one that is from Lance Armstrong's "LiveStrong" cancer awareness organization) with a multivitamin purchase. I try to wear the band whenever I am around the W -- I discreetly snap the wristband against my wrist at times to remind myself to mind my tongue and my feelings around W.
It works... mostly. I develop some good red marks from heavy snapping at times.
