Hi leo -
The first weekend was the hardest for me, too, but I felt so good once I got through it. I think we make it harder on ourselves than it has to be, though, because we get caught up in our imagination. We imagine that everyone is out having a good time - we imagine that we'll be bored or go crazy - we imagine what a drink would feel like.
Instead, we can use our imagination to think about waking up without a hangover, building a better life for ourselves, getting something done, trying something new.....
I've found that staying in the moment is really helpful. I don't do well when I'm living in my imagination. The good news is that is gets easier (and better).... if we can do it, you can too!
