Hello,
For starters it's important to not beat yourself up. I have smoked for over 25 years, it hasn't been easy but I have one month as of today. I did spend at least 6 months cutting down and in some people's cases that smoke a lot more it's important to reduce first so you're body doesn't go into shock, i believe. I'm not a doctor, but I do believe it needs to be gradual. Please remember that it's mostly about behaviors and the psychological effects of the smoking that really gets us hooked. I started to print off pictures of what a smoking lung looks like and put it on my fridge. It was a start.

good luck to you
you can do it, i beleive in you!!!!
