I have a close friend who wants to quit drinking. He's been in the habit of drinking daily for several years. I understand that quitting alcohol is one of those things that you have to really want to do to be successful, and even then it's a tough process. We have a couple of other hobbies that we share, and involving ourselves in those sometimes helps to take his mind off of drinking. But more often than not, he reverts back to his "one or two" drinks to make him feel better from the previous night's hangover. And usually that escalates to a six pack. What can I do to help him cut down, and eventually quit? I believe he is sincere in his wish to stop drinking.
