Welcome back Katzen and thanks for sharing your story. One of the most important things when getting sober is honesty, and I think your post was a very honest account of where you are with your addiction. I think the next step is to be honest with yourself and your husband about how bad things really are. It sounds to me like you will most likely need a supervised detox as yon have a physical addiction ( shakes, etc ). Quitting on your own would be very difficult and potentially very dangerous. You are also driving under the influence which is a danger not only to yourself but others on the road.
Why not tell your husband the real story? He can help you get through this safely.
