It's like breaking up with a BAD ex gifriend. Yes, after the breakup, she will tempt you... try to get you to come back... oh, the sex was good, wasn't it?... then come back!
The decision is how you handle it. Do you wallow in the temptation? Think constantly about how nice it would be to go back to her? Think, every night, whether or not you are going to give in and call her?.... and constantly torture yourself with these thoughts?
Or do you stand firm and make this a CLEAN break. Yes, you miss the companionship... but you KNOW that along with this comes ALL of the bad shit that came with it... the slavery, the guilt, the health issues, etc. Nicotine is BAD NEWS, do not let it tempt you. It is not good companionship, it is actually evil companionship that steals your health, your money, your time, your self esteem, etc.
And refuse to allow yourself to wallow in nostalgia for it. Instead, turn your back to it, and RUN.
