Oooooh yeah, I get this really badly and have been known to fall asleep at my desk over a paper several times! Like you, I'm fine if I'm doing other things like testing participants and writing papers etc, but reading sends me straight to sleep! I just try to save it for the time of day i'm less sleepy, and occasionally swallow a couple of caffeine pills (Pro-plus) to keep me going! I'm not saying this is the best solution, but I don't drink tea or coffee so Pro-plus does help me out with the caffeine boost now and again, but I don't make a habit of it! Best, KB
