1day - early on I just went to bed early. My body craved sleep to recover from all the abuse I had put it through. That lasted a few weeks. - I also forced myself to get up early and hit the gym - that helped me alleviate my stress and anxiety in a positive way.
Just find a way to get to bed sober each night.
I wish you the best in recovery - especially when you get to the point of realizing how many things you're missing out on because of the addiction.
