Addiction: A Brain Ailment, Not a Moral Lapse, by JANE E. BRODY. I've heard it before. And there's no easy solution:

[T]here is clearly not one route to recovery. Some addicts manage to kick their habits without any outside help; others require monthlong inpatient programs and continued reinforcement, either professional or lay. Still others may need a year of outpatient treatment plus aftercare. Many former addicts find that support groups of fellow former addicts like Alcoholics Anonymous and Narcotics Anonymous help them maintain their drug-free status.

Update

We usually have a donut on Sundays (for breakfast; for lunch we have my famous baguettes), but last Sunday we didn't, and last night I had a dream about a donut shop here that doesn't exist. This craving shows I'm a donut-aholic in desperate need of treatment. Is there a D. A. (Donut-aholics Anonymous)?
