My husband and children know. I told a best friend of 40 years because I drew away from her so much during my drinking time and I knew she would understand. I told another close friend because she kept bugging me about why I wouldn't go to the bar with her anymore and well that didn't go very well. Anyway, didn't mean to get off the subject.
My husband and children who had to deal with me when I was drunk and 2 friends, that's it.
I won't tell the rest of my family (aunt, cousins) or work people. I tell other family members I don't drink anymore because it was affecting my health (true) and work doesn't need to know.
