Keep using whatever worked when you first quit. Don't expect new rituals to take the place of smokeless right away. You know, it took time to get used to chewing or dipping at first, too.
Keep up your guard. Continue to plan ahead for situations that may catch you off guard.
Try not to slip, not even once. But, if you do slip, get right back on base.
If slips are frequent, or you are dipping or chewing on a regular basis, make a new quitting plan. Quitting takes practice. The smokeless habit can be tough to beat. Most users don't quit for good on the first try. Don't give up! Figure out what would have helped. Try a new approach next time. Talk to your athletic trainer or your doctor for extra help.
"The biggest reward is knowing that you did it." (Tony Welborn, former minor league pitcher)
