3 & 3/4 years smoke free, 30 year smoker, pack a day, more if up late or if alcohol was involved. Chantix got me off...rough patch 6 weeks in, used nicotrol inhalers..then switched to ecigs which are 100 times more satisfying than nicotrols. But, the nicotrol did it's job to keep me from losing my quit, so I won't knock it. Fact is..I'm OCD & need the hand to mouth..
