I quit a month and a half ago. It's freakin great!
If you use yahoo widgets they have one that counts the days since you quit. It also adds up how much money you've saved, how many cigs you haven't smoked, how much nicotine and tar you haven't ingested. It's pretty encouraging seing that on the desktop.
Good luck to all you guys quitting now, it was hard, but a very good choice.
