Did you manage to give up smoking successfully?

I discussed with my husband about ways to stop smoking. I used to but he still does, it's one of his "pleasures in life".
Would a hypnotherapist help, I asked him. No, he wasn't convinced.
I found it really hard giving up cigarettes and now it's been three years. He only smokes at work but if he feels the need for a ciggie at home he will go outside to his man cave - the shed.
