By Julia CExcept for the lozenges and e-cigarettes I've tried everything everyone else here has mentioned. Pre 1990 I even tried snuff & smokeless tobacco.
The only thing that's ever really worked for me has been nicotine receptor blockers like Zyban & Champix.
I'm on Champix now & on my 19th smokefree days. The cravings are gone, triggers are now very few, but what I have learned is I can't let my guard down. One cigarette & it's back to day 1. I've come too far to want to contemplate that.
I'm also on day 2 of a 24 hour virus. When I was a smoker, I'd force myself to light up & puff even when it made me cough so bad my lungs hurt. It was a relief today not to feel the urge to do this to myself.
(P.S. DOATT = Day One All The Time)
