Congrats to all of you who have quit.
January 1st of this year will be 2 full years for me not smoking.
I gained about 25 pounds as well, but that was lack of excersize and not watching what I was eating.
If you quit, you've gotta watch what you eat and stay off the treadmills! They are useless.
You've gotta put in the effort and run outside, if you want to lose fat and build your cardio.
Good luck to all!
