Oh we usually watch TV after 6 pm:D. I don't necessarily practice what I preach. Especially with all the sports after 6. But the 2-3 nights a week when I don't watch TV after 6, sleep is so much better.
This is my issue too. If I don't watch any TV after 6pm, sleep isn't that bad. Minimize computer and phone use after that time. Early dinner. Take a shower before going to bed. All this worked much better than any herbs and medications.
