I quit about 2 years ago....actually because I was broke for a week
Anyway: as l3fty said, get past the first 4 days and you are good to to. Next try to reach 7 days, then a motnh, etc. That way you have small milestones and it keeps you focused.
Besides that: quiting ain't something special Just don't smoke...and don't tell yourself all day, that it's hard....cause that way you think about smoking all day. just ignore it.
Good luck mate. You can do it
