I've had tinnitus for almost 20 years. It sounds like a high pitched dentist drill 24/7. I can't hear the tea kettle whistling away when I'm in the next room. I haven't gone to a doctor about it because I figured they can't do anything. I have a hard time sleeping. I get maybe 2-3 hours a night on average. I wear ear plugs and a helmet when I ride my motorcycle. I don't wear ear plugs when I: travel on airplanes (a lot, for work), make green drinks in the Vitamix, drive my Mustang with road noise. Should I be wearing ear protection for those things, or will it make any difference at this point? Also, how can I get a better night's sleep?
