My dear brother, forgive me if this thread brought up any anxieties; I didn't realize how serious insomnia could be. There are some really great machines out there that produce all types of noises from a rainforest, thunderstorm, ocean surf, white noise, humming, woodland stream, heart beat, ... Before I was married, my housemate used one of these that he set to white noise. He turned the volume up pretty loud. He swore by it. I use a small, portable fan/heater that produces a nice (somewhat loud) humming noise. Another option you might try are comfortable foam ear plugs. Noises don't bother me but light does, so I wear a sleep mask (the inexpensive kind at Walgreen's). I pray that one, or both, of these options will help you out.
