At the beginning of this sobriety which is new (yet again), I spent a whole afternoon structuring the "problem" I have with alcohol. In structuring a problem one has to look at the "roots" of the problem.
What I discovered at the root of my problem? Persistent loneliness and fear of intimacy. Quite a conundrum...therefore alcohol was my "solution" to both. Pretty lousy solution.
Incidentally, you have already noted some barriers to the "sobriety" solution (social pressure, tsunami of emotions etc).
No..you are not alone in this...at all.
