I think that the issue is not just flourescent lights. I think that many of us are hypersensitive to a lot of environmental things. The computer could be electromagnetic field hypersensitivity. I am very chemically sensitive, and and am aware that when I go into a lot of places like hotels, malls, even schools (I am a consultant and go in and out of schools), I feel exhausted and foggy. It's not just flourescent lights - for me it's a zillion chemicals in the environment.
