Hi Pinot,
I'm glad you are here and posting, and planning to stop drinking. I also think today is a great day to quit. Sunday is the first day of the new week, you will wake up sober on Monday for the first day of the work week, and will be one day further on your journey to sobriety.
I'm sure to you it seems your husband isn't being supportive, it is possible he is doubting whether you will actually stop based on the past. I have had several day ones as well, and decided this year would be different and stopped drinking NYE so January 1st is my day one. It hasn't always been easy, but I have been vigilant about my plan and when thoughts of drinking have popped into my head, and unfortunately they have, I did something/anything else: went for a walk, played outside with the kids, read, journaled, logged on here...
You can do this, and it is worth it. Make today your day one.
❤️ Delilah
