@MMS21 I've read that the most effective technique is to just decide that you'll never smoke again (with no other behavior changes required), discard any cigs or smoking implements and push through the withdrawals (they get very bad for a few days and then they subside) and then you win.

I would love to do the same with proprietary software completely, but of course the government ensures that it's extremely difficult to give up certain brands of proprietary software cigs.
