I think nicotine is so bad because its usually a life long addiction with so many memories tied up in it. I've been a smoker for most of my life (33 of 46 years), and don't really know how to be a non smoker. I don't feel like me. But pain?? - blah - it aint bad. I've felt much worse, and where my thoughts may be be sluggish during withdrawal, I can do anything I normaly do. The physical withdrawal is nothing, and with all the alternative delivery forms (gum, patches, lozengers, inhalers etc.) its a cakewalk to wean oneself from nicotine. Now the psychological adiction is a biatch. I'm a smoker - always have been and always will be even if I aint smoking. I've smoked long enough so that if cancer is in the cards, quitting noww probably won't stop it. I'm quitting to try to prevent becomming a heart disease invalid. I'm getting to that age where heart disease is definite threat.
But boy I would LOVE a smoke right now...
