NICE!
I quit 5 weeks ago cold turkey, so I know just how you feel right now buddy. I smoked ( pack a day ) for 10 years, and incidentally, am also 33 years old.
The worst is over, but the rest of this week may still be tough, so stay strong. After 2 weeks, it's a breeze.
My best advice would be to do something with your hands especially right after eating ( hand wash the dishes - go throw your pottery right away, whatever...
And already breathing deep feels sooo great & I smell better ( both ways ) too.
If you need any support when you are craving, let me know and I'll do what I can to distract you.
Great Job!
Joe
