Go cold turkey, and keep yourself away from other smokers, or at least where they smoke at. Remind yourself that cancer, black lungs, and early death await you if you keep smoking.
Chantix worked for me.
I agree with you 100% tho. If you value your life, whatever it takes to get off the smokes, do it. Do it now, not when you doctor starts talking to you about your options in portable oxygen carts.
