I have this reoccurring problem. It is 9/10/11am and I am at a meeting where I sit either one chair or two away from a large projector screen. With the fluorescent lights off, the screen is bright in a dark room. I get drowsy and my head feels heavy. My eyes go off in their own directions until I try to snap out of it. Typed words become illegible and challenging to try and read. I have noticed this in same behavior in a meeting where the projector was used while fluorescent lighting was left on. When we break, and I get a chance to walk around, I can snap out of it. What can I do to avoid it altogether?
I eat breakfast each day, usually shortly after 7am. I get 6 to 8 hours of sleep. I sometimes drink coffee but it doesn't seem to help. I believe it is some sort of eye-strain related to sitting too close to the projector screen, but I don't know. What can I do to stay alert in meetings?
