Kind of the same here Owl, in the daytime I cope but as soon as it gets dark then the urge starts!
I also live alone and suffer from depression, I keep falling at day 2, and always the same thing going through my mind "what's the point"
For me trying to give you advice would be like the blind leading the blind but all I wanted to say you are not on your own trying to deal with quitting alcohol!
Ps, last night I consumed 2 large bottles of cola to try and stop me from drinking, it worked but I would not recommend it. I sat in the chair with chronic stomach cramps and making noises for hours like a balloon letting out air.
