Well, I'm bumping up an old thread because I'm having a similar issue. I get plenty of sleep at night (8-9 hours average) and I just can't seem to stay awake when studying. Its fine if I'm DOING something while studying (rewriting notes) but I spend half of the day listening to podcasts and I just CAN'T stay awake when I'm doing that.
Yesterday and the day before we had seminars and I slept through the entire thing, both times. I wasn't trying to sleep, I was trying to stay awake - the stuff was pretty important for me to know for clinical rotations. I just couldn't do it.
I'm beginning to think theres something wrong with me.
