Brief Summary

Prospective observational crossover study of 150 consenting adult patients who are undergoing chronic pain management. For insomnia treatment, each patient ingests prescribed doses of Lemborexant or Zopiclone or Clonidine on alternate nights. Each patient uses a special validated sleep diary to collect data including pain score, sleep score, sleep duration, sleep medication type, and adverse effects. Each patient completes the diary for 3 continuous weeks. Pain is measured using the numeric pain rating scale. Sleep score is measured using the Likert sleep scale. A change in the pain or sleep scores by 2-points is considered significant.
