I struggled with insomnia, night terrors, interrupted sleep, etc. for my first month of sobriety. Drinking wasn't a concern for me, but my mental well-being, my sanity, was something to be concerned about. After not sleeping for a few weeks I found myself spending the weekend in a mental hospital for psychiatric evaluations.
Have you talked to a doctor about this, or considered it? I found that taking a prescribed medication helped immensely, and restored my sleeping pattern in a short time. Please give some thought to seeking help.
