I've been trying to figure what I need to do to sleep through the night. In desperation one night at 2 am, unable to sleep, I pulled out some sleep products I hadn't used in a while. One used to help, but no longer did so. The other never did seem to help. Guess what? The one that never helped made a difference! I now keep it next to my bed in case I wake up during the night.
Those who never have sleep issues just don't know how lucky they are!
