Noise sensitivity
When it comes to having severe CFS, one option in dealing with noise sensitivity is "white noise" (to block out surrounding noise). I have a Walkman which will play continuously (it keeps turning the tape around). If noise is bothering me, I insert a tape which features the sound of waves.
A "Do Not Disturb" or "Quiet Please" sign can let other householders know when you particularly want quiet. Some people with CFS/M.E. watch television with the sound off (sports and nature programs can be good like this). Also, try using subtitles on your TV rather than sound if available.
