I have trouble sleeping also. I leave the TV on Sleep mode and I fall asleep. Also, try running a fan, turned toward the wall, or oscilate so as to not blow directly on you, the noise from that helps also. I have had the noise for 6 months, and I have a left side AN which I am in wait and watch. You have to try to ignore that noise. That is not always easy, but, you need to try, or it will drive you absolutely batty.
