Hi Construct - I'm an artist, too, and I know what you mean about using alcohol while being creative (although looking back, it hurt my work more than it helped). I've been making a living at it for 20 years, and because of the economy, things have been extra stressful. I didn't know if I could sit at the easel without drinking.... (still haven't quit smoking, though, so a big congrats on that!)
I spent the first couple days in bed, too.
The good news is that at 6 months, I have no desire to drink (the obsession goes away slowly, but it does go). I'm also producing more and my work is getting better. Are there days when I can't paint? Sure.... but they're fewer and further between now.
It takes a while for the energy to kick back in, too. But each day it gets a little better. Hang in there and be patient with yourself. You're worth it....!
