Summary

This study tests a type of hypnotherapy called E2R for people with chronic insomnia. It compares E2R to usual care (like sleep medications) to see if it reduces insomnia severity. About 136 adults with chronic insomnia will take part, and the goal is to find a safer, non-drug option for better sleep.
