In my early sobriety, my anxiety peaked every night at 11:30pm on the dot. It was eerie. But after I realized that it started to calm down because I'd get super anxious and just say, "Oh, must be 11:30," look at the clock and see that it was, and start putting myself to bed with a book and talking myself through it. Once the pattern was obvious it made it less powerful. I hope the same starts to happen for you.
