Hang in there Kimberley!!
When I quit a while back, I remember it only really sucked for about a week. And as long as I had something to do, it wasn't bad. I was times when it was second nature to smoke...in the car, at lunch, etc that it was bad. I would just set small goals, like, just making it until lunch or just making it til I got home, etc. Once I got there, I'd move the goal up. After that 1st week I felt such a HUGE sense of accomplishment that it drove me and I couldn't wait until for the next 7 days so I could say it had been
2 weeks.
You need to find something you can do to burn off nervous energy, cause that's what it seems like it creates...
