You're not being silly at all, Vellamint. I think most people wonder when the med is going to "kick in" and often believe it "isn't working."
Honestly -- and I'll bet that those on this thread that have taken that big step with Chantix of stepping over to the nonsmoking side will agree -- the med REALLY kicks in and "works" when you put the smokes down. The med, while smoking, never really got me to the point where I didn't want to smoke. If the cigs were there, available, with a lighter and ashtray there, by golly, I would smoke. They tasted different, and I often couldn't finish a whole one in one sitting, and I guess subconsciously my brain wasn't getting much from them.
Where the med is amazing is when you get rid of the ashtrays, the lighters, smoke or drown your last smokes and there you are, not smoking and not having smokes available to you, you're just not going out of your mind wanting one. Craves become thoughts and not really much else.
Where the med stops, however, is with the actual habit -- IMO, anyway. You'll need to for sure have a plan of action on what you're going to do during those times you would have smoked, i.e., on the phone, driving, after meals, coffee, stuff like that. But as long as you've got a "plan" to help you during those times, the med turns what would have been a blinding, searing, "I'm going out of my mind for a cig" crave into, "Wow, sure, I'd like one, but I can make it without one" thought.
I was extremely skeptical. I loved smoking and felt I had to quit -- not so sure I "wanted" to quit. I took the med for 15 days and still smoked because I kept waiting for the med to work. The night of day 14 on the med, DH said he was ready to quit and that I could keep smoking, but I'd be on my own. I remember making a deal with myself at that time, that I'll finish that pack and if I'm going out of my mind for a smoke after that, I'll throw in the towel and go get some smokes. I even left my ashtray, lighter and (empty) cigarette case there in the garage. I was that convinced (a) I wasn't ready and (b) the med wasn't working right on me.
That was 66 days ago. That, "I'm going out of my mind for a smoke" feeling just never hit. And I'd tried to quit so many times before with patches, gums, Wellbutrin, cold turkey, weaning, hypnosis, behavior modification. I was too weak to deal with those just awful craves and resulting depression when I realized I couldn't smoke.
You are going to be really surprised tomorrow. And if you're not ready tomorrow, don't beat yourself up. Pick another date or let a date pick you, i.e., "This is my last pack. After I'm finished with this pack, I will not buy any more."
Please let us know how it goes for you!!!
