I have had the experience of going from one addiction to another. I would suggest you find your local AA chapter and go to meetings. If you start smoking again you will probably then have two addictions. It is great you are seeking help before things get any worse. Because you say you can't do without buying and drinking the beer you are already an alcoholic. Question is do you want to continue this path, If not call AA or some other group for alcoholics. Good luck to you.
