DEAR DOCTOR K: I'm doing my best to quit smoking, but I am really struggling with the symptoms of withdrawal. Do you have any advice?
DEAR READER: You're not alone. Beating an addiction is not easy, but you can do it. And there are new treatments today that make it easier to do. Physical withdrawal symptoms make stopping any addictive drug uncomfortable. Nicotine -- the addictive drug in tobacco -- is one of the most difficult to beat. Withdrawal symptoms are the reason many people don't manage to quit smoking. These include intense cravings, irritability, fatigue and inability to concentrate. They can begin within a few hours of the last cigarette.
