I think we've all had MANY mornings of waking up and saying, "NEVER AGAIN!" You're not alone on that one.
Congratulations on taking the first step toward a sober life. I'm sure it was difficult to hear those words from your husband, but at least he loves you enough to be honest with you. It is very difficult for non-alcoholics to understand why we can't "just stop." I heard that many, many times (and this came from my alcoholic husband ... duh). If it were really that easy, there wouldn't be so many of us out there. I used to say the same thing to my alcoholic parents and really didn't "get" it myself until I was in the same boat and the boat was sinking fast.
You'll find much support here but I'd also recommend some type of program to help you ... AA, AVRT, SMART, etc. A program can help guide you and give you the tools you need to get and stay sober. Programs like AA can also give you face to face support, which can be enormously helpful.
Welcome!
