My friend dipped for a bit, would spit in a Pepsi bottle..one day, working around his shop, he grabbed a sip from the *wrong* Pepsi bottle and puked for a good long while. He never chewed after that.
His advice to people wanting quit smokin has always been to lick an ashtray...lol
Poor poor man
Im lucky, never smoked...bleah, just not my thing. Chew...not thanky! Dentist showed me some neat gum disease pics once...bleaaah
