I still occasionally wake up pissed off at myself....no, that's not right...I'm always pissed off because I woke up, but I get doubly pissed off when I've been dreaming that I started back smoking, and I haven't smoked in decades.
It does become part of your routine, and you don't really notice how much you smoke until you start counting the number of packs you put away.
Shoot, if you're a pack a day smoker of Marlboro reds or any other name brand, save the money you spend on smoking and after a year you could easily pick up 3 Serostim kits with money left over for BW and some darts.
