How to break the habit??

I'm trying to quit cigs at the mo. I drive a van for a livingwith short drives between each delivery and built up a habit of lighting up between shops, not smoking all the cig, usually putting it out b4 the next shop. It's at this time that I crave a cig, at home and out with the mrs shopping or having a pint I'm ok. I've tried replacing them with lollies but went through a bag of about 50 in two days. I have smoked in the van but not at home.(I'm on patches btw). Any advice.....please...all answers appreciated
