I've been a 3+ pack a day smoker for 35+ years. Haven't had a smoke for 45 hours.

Good on ya! Keep it going.
I quit in Iraq ****, 16 years ago. For me I had to replace the mechanical movement/oral fixation. Oddly enough, sunflower seeds seem to help with that.
Congrats! Think of all the car parts you can buy with that dinero!
