Some great and helpful comments here. My first session of rehab has uncovered some truths. You are right there is more to it than just alcoholism but without alcohol in the frame things get easier to deal with, my behaviour is more controlled and my conscience is intact. Indeed my wife is a saint and in all aspects of life I don't know what I'd do without her. I sincerely owe it to her to mend my ways.
Thanks again for the support.
