Hi Holds -- my first few months of sobriety were kind of a rocky time, too. I had anxiety and lots of emotions surfacing, that I used to stuff down with alcohol. It also took awhile for my sleep to sort itself out, and my hunger and food cravings were wacky for awhile.
That stuff does calm down with time, at least in my experience. If you can hang in there with it, I think and hope you'll find it was a good trade-off. Staying sober, we can take advantage of all kinds of tools and treatments for anxiety and health issues. Drunk, I had no chance to make things better.
