Anyone who has managed to successfully quit smoking.. HELP?

I have smoked since I was twelve, I'm now twenty and I want to quit. The problem:I just looooove smoking! I smoke two packs a day if I'm trying to be good, four if I just smoke all I want. I realize the health impacts. I have seen pictures of a lung ridden with cancer. Grossed me out but did not make me quit. I tried the patch, the gum, the inhaler, been hypnotized, tried cold turkey, DID NOT WORK! I even drove an hour to a nature preserve, hiked thirteen miles into the middle of nowhere, leaving my beloved ciggarettes behind, I hiked back that night and drove to nearest gas station to get a smoke. I need help!
