My hubby is a trucker and even though he quit smoking eons ago, the hand to mouth habit never left. He became a food popper. Always popping grapes, cheerios, gummy bears, fruit loops, into his mouth. After gaining 20 or so unwanted pounds (he's an athlete when not driving), we rigged him up with a Zero nicotine fruit eliquid inside a tiny bottom feeder called the Old Goat, with a Cisco 306 at 1.5 on it. Within a month he regained his weight control, and his food popping habit subsided back down to manageable. He hasn't had to use it in over a year, but it's here at the ready when he needs it. He wore it on a lanyard (those drops from the truck ruin many an item, especially thermos's!), plus tucked it inside his shirt pocket. He carried extra batteries and an extra atty in his briefcase, never had a problem.
