Champix works but, yeah, I'm back on the cigs after four months. For me, it's a case of terminal curiosity, I started to wonder what nicotine would feel like after four months of being clean - needless to say it felt GOOD. The process goes something like this: Hmm, nicotine! "Can I have a drag", then its "can I have a cig", and that quickly degenerates to "Go buy your own, I'm sick of giving them to you, cheapskate bitch!", to "Can I have a pack of Winfield Red 20's kthxbye." Smoking bongs didn't help either, and I can't carry my vap around with me wherever I go.
I think, ultimately, breaking an addiction is as much about saying no every time, not just getting through the withdrawals. I still think Champix is a wonderful tool but when I started taking it again (never finished the full course so still had a pack and half left, and you can only get one subsidised script a year on the PBS) I wasn't as committed to going through that first 48 hours, so kept smoking well into the second week. So instead I've decided to just smoke for a bit longer and keep a pack on reserve for when I am properly motivated (ie. my lungs hurt so bad and my heart flutters like I'm about to have a heart attack) to just say "fuck it" and do it, get past those first 48 hours or so. At least that's the plan. The comment directly above this one though gives me a little faith, maybe you have to fail a few times to know what success is really about.
