My sobriety was fragile in the early weeks. I had to protect it. But since I was a always a home-alone drinker, I had to get used to being home alone without drinking. It took some determination but I got stronger with more sober time. Now I can go anywhere and do anything without feeling at risk.
Give yourself more time to strengthen those sober muscles. It gets better. After some time sober, you'll find you don't think about drinking as much as you used to do.
