I hate fluorescent lighting. I work as a special needs teacher and was sent on a really important three day course in January which cost my school a lot of money and was really hard to get on. ( the places were like gold dust) Anyway, I got there and sat down and within an hour felt like I had the flu and jet lag at the same time. There was a weird pulling sensation in my head and it felt like something was moving around in my brain. When I looked up at the ceiling I counted 22 fluorescent strip lights in a room approximately 20ft by 10ft. Needless to say I sat there for three days like a zombie taking nothing in and feeling so tired I thought I'd taken a bottle of tranquilizers.
At the time I beat myself up about it thinking I was stupid for not taking any of the information in, especially when others seemed so alert.
I now know what the problem was.
