Good luck, My wife tried Chantax and had crazy delusions when I was off on business trips. She thought people were in the house at night... She ended up using the electronic cigarette, she says it has a lot to do with just the hand and mouth thing. ( I offered a great solution but she kinda balked)
She gets them from premiuimegigsite and has been off since Key West. I still laugh when she takes a puff and then sticks it in her pocket!
