Yeah? Well I hate working, but it must be done.

I believe that you can quit, like what other people have said

Tell other people

That way theres peer pressure on you to quit.

Also, find some nice but really anti smoking friends and hang out with them frequently. Things like that can rub off. As for the hand thing, take up knitting. It helped a guy I know. (I am completely serious). If knitting is too cool for you try tapping out tunes on a surface, you get addicted to it and then your hands are occupied.
