As a 16-year (successful) member of the original 12-Step program, I suspect you have a problem other than tobacco. Although you have to make this ultimate decission, I relate what you say to what I've seen, many times. Trading one addiction for another is common and if this is you, I suggest and hope that you will get more information about and treatment for the drinking question (problem). You obviously sought more info regarding your smoking problem (addiction) and probably wouldn't be in this forum had you not made that decision. So it is with alcohol.
One does not 'normally' just start binge drinking becuase of anything except a loss of control over alcohol. Normal drinkers don't binge and normal drinkers don't question their drinking. Once I questioned my drinking, there was no return to 'normal.' Make no mistake, I am talking about a progressive, fatal illness.
We all acknowledge that smoking will (can) kill us but the addiction process tells us we will somehow excape the consequences of smoking. This results in smoking usually taking many years to do its damage to our hearts, lungs, etc. Alcohol on the other hand can kill quickly, whether you are addicted or not. When someone becomes addicted (alcoholic) to alcohol, the same process tells then they will escape the consequences. . . that they are 'normal' drinkers. The result is that facing up to the drinking problem usually takes a major, life changing event . . . loss of employment, marriage, driver's license, jail time, etc. With smoking, these types of events rarely happen to the smoker as an inspiration to quit. The decision to stop smoking just doesn't usually come from an immediate situation.
Although I am new to not smoking (4+ days), I do have the 16 yrs of knowledge that my other program has taught me. As a result, I have (and use) the support tools already in place. There are many in (my) the other program that have successfully quit smoking, too and most of use that support, wisely.
I hope this helps you decide a course of action and if I can be of further help, let me know.
