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.
