You have taken the first step!
I quit 3 years ago next week and it was the best decision I ever made.
My recommendation is use the money you would have spent on cigarettes and either invest or treat yourself as motivation.
What about getting a money box for your son and putting the money away for him?
If ever feel like you need to have a smoke, pour a glass of water and keep drinking until you are full.
That's what helped me in the beginning :)
Dude, congratulations that is awesome. Maybe I’ll have to invest the money in crypto for Harvey. Thanks for the advice as well :)
