try doing The Master Cleanse - it rid me (i think permanently) of my nicotine cravings. they are not there anymore. i don't feel empty either...there is that full and yuck feeling when i even look at a smoke these days. before i used to feel hollow and get panicky. i've actually been permanently quitting for the last year, but it feels like the mc completely cleaned me out of my habits. maybe it destroyed those receptor cells responsible for releasing the craving? i even stopped caffeine for a while...but i have to have one vice! ;-P
i've been smoking off/on for 15 yrs! my boyfriend is next to quit!
