I am an EXTREME anti smoking advocate(let me say right away I can understand, tho, how hard it would be to quit from the studies I have heard) and my Mom quit 5 years ago after 50 tears of smoking heavy because her 2 non smoking daughters wanted to avoid being anywhere near her. It sounds hard but I can smell a smoker, literally, from 10 feet away(and they're not smoking) and it makes me want to vomit. Mom quit using one of the common patches and her VERY strong will. my point IS- you CAN quit if you truly understand how gross it is to non-smokers(they will tell you that they can't tell but it is SUCH a lie) and not to mention the current cost. I knew a man that had taken the chantrix and had the nightmares,etc but he was pretty mentally unstable to begin with.
