Thanks so much for your input. I will look into potassium. I take magnesium and zinc at bedtime. My best guess is - probably not the Lunesta, but lack of the Klonopin/night anxiety not being controlled. I had horrific night sweats prior to menopause - worse than now, and I was taking Ambien for sleep issues. Once they switched me to Klonopin -no more sweats and better sleep. However, now that I am no longer taking a benzo, I feel more balanced, mentally and physically. I think my brain is healing, but that anxiety comes back at night. That might explain the sweats - but not the cramps.
