Welcome, friend! You've made the greatest, most life-affirming decision possible. I quit at about the same age, and it absolutely transformed my life. Warmest congratulations on your freedom!
Be vigilant and be prepared for the challenges ahead. For most of us, recovery is a long and often non-linear process; thus, even when a quitter has some time under her/his belt, there can be rough, unexpected stretches. So it's good to develop some strategies of things to help during those difficult times. For me, exercise was a crucial tool, but find what works for you.
Don't hesitate to reach out here if you need some help--you'll find plenty of folks are eager to help. We've all been in your shoes and admire what you're doing.
Cheers--
