Ph.D. Changing an addictive habit usually means coping with sometimes relentless urges.
Urges often dominate thinking and interfere with the daily routine.
Many people give up because they believe they can't function without their habit. Remember that urges, in and of themselves, are normal. We all experience craving in varying degrees every day. Because your habit has been important to you for a long time, it is unreasonable to expect urges to vanish completely. If they do, don't be surprised if they occur a month or two down the road.
