I live on my own and so know the problem every evening after work, reasons 1,4 and 5 are basically the same thing, and your issue won't be solved by doing nothing, the problem with simply taking alcohol out of your life and not changing anything else is you end up with a lot of free time, sitting around thinking about alcohol, and that's a recipe for disaster.
So what we need to do is change our lifestyle, pre plan things to do each evening, that's difficult at first as we probably didn't expand our interests/hobbies over the years, we just filled the time with drinking, right?
But that needs to change, we need to carve out a new pattern of life, what do we want to do with our lives, now we've dealt with the issue of alcohol!!
