There are no doubt many of us who are there or have been there.
Many years ago I owned a convenience store and would bring home a bottle of wine to share with the wife each evening after I locked up. One bottle became a bottle and a half which became two bottles until the day the wife said “that’s enough!”
We still have a drink occasionally but more often than not prefer a cup of tea.
I’ve a friend who’s been an alcoholic for the past forty years; he gave up drinking about four months ago for no apparent reason. What he had and has lost had to be seen to be believed!
