Hi there. I fell off the wagon, too. I quit for 18 days and then I went on a three day drinking-festival. I'm back on day 7. For me, it does help to get out of my environment and old patterns. Right now, I'm sitting in the mountains of northern New Mexico enjoying the peace. The trouble is being at home around all my deeply ingrained patterns. I'm not looking forward to that.
I think I remember that you mentioned you are not into AA? I find it can help simply because it give you something to actually DO. So much of quitting drinking is about NOT doing something (which is torture). I started attending meetings that were OK, but I'm still in search of the perfect home group for me.
Have you ever tried meditation? If you are in NYC, this is a great secular buddhist organization that has all kinds of workshops.
