This is the first time I've ever posted to a message board, but I'm hoping this will be helpful to someone. I started having the worst insomnia a couple of months ago. I was exhausted but still couldn't sleep, sometimes for 36 hours. I tried listening to soft music, exhausting myself, everything. I didn't want to start taking sleeping pills, but I thought I might have had to. I was a mess! My husband noticed that my sleeping trouble started when we fixed the problems our house was having with dampness. Before that, the dehumidifier was running almost constantly, providing never-ending white noise. So we bought a noise machine (some of them are very expensive, but mine was around $30) for me to put on when I went to bed. The setting I use is ocean waves. Without any birds or other sounds it's really just a cycling, monotonous noise. Well, it has helped me so much, I just had to let other people know. I still go to bed fairly late and wake up late as I have ever since I got sick, but now I'm able to get to sleep fairly quickly every night. Yay! I know everyone is different, and this might not help everyone, but it seems worth a try. I think they make CDs with these kind of sounds, too. For me it was important to get something as close to white noise as possible. Good luck!
