RE: keep the eye on the prize
Congratulations on your decision to stop smoking. As for finding extra money in your pocket.. while it should be there, unless you set up a saving jar, where you deposit the amount of money in that jar that you would normally spend each day.. it seems to disappear into the every day costs of running a house hold.
Its a nice idea to do something nice for the better half. Not only will they appreciate the thoughtfulness of the gift, they will also appreciate the non smoking atmosphere.
