Its tough.  My wife and I put into a jar every week what I was spending on cigs.  Decided I would get to spend it on whatever I wanted after I had quit good.  Man the cash added up fast, even 30 years ago.  I spent it on r/c airplanes.
Like I said it was tough.  Had hemmoroids from the stress, headaches, and pretty grouchy for a couple weeks, then got better slowly.  Keep at it and you will whip it, don't let it whip you.
