Good luck. I smoked for years and as much as 3 packs a day. Not an easy thing to do, but stick with it. I does get easier. My trick was chewing a stick of gum whenever I normally would have had a smoke. Seemed to help. Focused on the chewing.
I have only had two that I felt I wasted my money on, the Sig P250 and the Sig P250. Cherokee Pawn had them for such a great price a couple years ago, I bought two. :(
