FYI, for me, Chantix is a quit smoking wonder drug, it made it surprisingly easy for me to quit my 15 year pack-a-day addiction.
Easy to reduce on because you know exactly how many milligrams you're taking (like methadone or something) because of Swedish labelling rules. I'm hoping to be off snus within the next three or four months, but there's no big hurry because it's pretty cheap and very safe in comparison to other tobacco products.
Internet ordering directly from Sweden is easy, and some of the fancier US tobacco shops are starting to carry it - so you might get lucky.
