Insomnia for 15yrs, wake at the end of every 3.5 hr cycle. Benzodiazepines are ADDICTIVE! Initial was Ambien which my Dr refused to renew after 3 yrs due to side effects; switched me to Ativan, not perfect but ok, withdrawal produced symptoms of heart attack, last was Belsomra, expensive, after 2 months I had difficulty completing sentences in conversation. Best solution has been combination of THC and CBD in an oil tincture, lots of fine tuning to trade off sleep vs sluggish next days. A natural product your body can deal with unlike chemicals. My wife uses THC for relief of stenosis after a Laminectomy w' cage, hip, and knee surgery.
