Thank you CupofJoe. I do know it is early days. It's been decades of drinking too much and only God knows when I crossed the bridge to alcoholism. But your message gives me hope.
Socialising (the little I do) is not a problem for me. Nobody around me is a heavy drinker. I was hiding all my drinking. About 100 units a week, with blackouts almost every day. And nobody noticed! So the danger is everywhere. It is not about going to a bar. Actually that's the easiest part. I hated it. Had to find time to drink before, then (last few years) I would add little bottles of wine to drink in toilet, while pretending to nurse slowly a drink like everybody else.
I drank alone and I drank with family around in my house. Only in the evening after making sure everybody was fed, the house was clean, my job completed. Kept a strict routine that made it look all normal, even when I could not remember half of my evenings. Somehow the routine was so strong I managed to follow it even when completely drunk.
Husband never noticed either. So I am forever vigilant because I can hide my drinking everywhere from everybody. It is not about the environment. It is me.
Thanks to everybody who read and the replies. It is good to let it out a bit.
