Glad you found us Loulou.
Your husband might not be as in the dark as you think. Mine knew more than I thought he did. He eventually became my biggest support.
Work is tough. You could just tell them you are cutting back. You will probably think more of it than anyone else. In my experience, people really are only worried about their own drinking. Good luck.
We're here for you. Congrats on the 4 days. That's big stuff.
