I second that Samb… Well done girl, keep it up… 
I am like Kev. Being a heavy smoker, I was well chuffed to give up for six months… had a row with the (Now) Ex, and started again 
… gave up again for two months, then hit a low point 
… visits to the docs and everything, and hence, started again…
But after xmas… New years resolution, I’ll have a new Job, new girl …(hahahah.we’ll see!!)… and a whole new outlook on life , so I’ll be back on the Zyban, and quitting once and for all… 
So keep up the good work Samb… you can do it girl…
