A little trick that works for me.
I keep a fan in my office and one in the house.
When Im out or in the car I dont notice it.
When I get home I hit the fans.
When I get to work I hit the fan.
If all else fails, I keep a PDA with a built in MP3 with me all the time.
If someone else is ther talking to me, I dont really hear it.
So basically, I never have to worry about it.
I get so pissed when I go to a hotel and forget to brink my fan with me, I cant sleep I just lay there looking at the celing (little flashy lights every where till Ive been in the dark a while) and listen to the ringing in my ears while I look at the flashy little lights.
Its like a permanent LSD trip some times.
