I wish you only the best of luck in your struggle. Sometimes it is a blurry line that separates typical or social drinking from habitual drinking. If I had to guess you could be in that grey area. While, I can't imagine drinking every day I know of people who couldn't imagine not drinking every day.
I'm a bit concerned about not telling your Wife about your plan. Frankly, from my experience: People who drink, enjoy the company of other people who drink. I've had someone actually get angry at me because I insisted on refusing a drink he was offering. While I'm not saying that your Wife fits in the same category as that fellow, I do believe that being explaining your reasoning and goals might help her to understand why you suddenly changed. I can't imagine making a significant change in any of my daily routines without it causing some kind of concern in my Wife. If she also drank (along) with you, I think you really should explain that your stopping for a while. Hopefully she will understand and be supportive.
EDIT: I gotta say that initially I thought that you just had a drink or two each day and later I read that you have a few more than that on the weekends. Now I notice that you are saying 'X days sober' in your daily 'count'. That is a big difference. I'm still not sure that I'm understanding the entire situation.
The entire situation is this: I've had the willpower to lose 80 pounds, stop smoking cigarettes, stop using cannabis (among other drugs), and get a two-year gambling problem under control. I have my spending under control, and I have $30,000 in savings with plans of purchasing a house by next summer. I
have the willpower to do or stop the things I want, but when it comes to alcohol, it seems like I have none. In the last 6-7 weeks, three days without some type of alcohol is the longest it's been. Most days I tell myself that I'm not going to drink, but by the time I get home from work I end up having 1-3 drinks. I have an addictive personality I guess, but I've been able to give up other potentially addictive activities, so why is alcohol addiction so difficult for me to break?
I've told my wife as many times as I've told myself, but I think she's gotten to the point of not believing me anymore. Don't get me wrong, as long as I keep my drinking under control, everything is fine. She is Japanese, and has told me that she often went out for drinks with co-workers after work multiple times per week, and so she doesn't really see what I'm doing as a problem, as long as the 1-3 drinks each day doesn't turn into the 6-12 it is on the weekends.
With all that said, I guess this thread is more for myself. Instead of crossing off dates on a calendar or writing on a notepad, I can just change the number on a counter each day. Plus, I feel there is some accountability here, as I could just toss the calendar or notebook I'm using and not think twice about it, but this thread is public domain. Some people are rooting for me, some people probably think I'll fall off the wagon anytime now. Ultimately, I could just lie to everybody, but that would be pointless after giving out all this personal information about myself.
I hope that clears things up for you.
