I think I've had chronic insomnia for about 20 years now. I sleep 5 or 6 hours on good nights. Sometimes less. Don't have trouble falling asleep. The prob is waking and tossing and turning. Agree that the problem is probably psychological combined with aging. Since i cant forsake work, computer and cell phone screens for a year on a beach in mexico(which I think would fix the problem) I'll try the app.
