I like to refer to cigarettes as vegetables because they are mindless and numb...yet we, who have functioning brains and free will allow ourselves to be controlled by them. I like my freedom too much to allow this ball and chain to remain around my leg.

As for quitting "cold turkey" if you want to....of course you must WANT to. It's all mental. If you really want to quit, any side effects will be minimal and easy to overcome. After a few days they disappear completely.

It's like jumping into a pool that's a little chilly. JUST DO IT.
