Congrats to you.
I also quit smoking ! I started smoking in Nursing school over 30 years ago.
I was hospitalized in December for a total knee replacement and spent 11 days in the hospital & rehab and decided there was no good reason to start smoking again when I got home.

I still have the urge to smoke but I have resisted so far. It will be 3 month smoke free on March 13th.

I haven't even tried to figure out how much money I have saved.
