My Professor's Lecture Is My Nap Time Schedule....

So I've got this class with the most boring professor ever. He lectures in this monotone voice that could put a sloth to sleep. Like, if someone asked me why I always wake up at 3 PM sharp every day on weekdays... well, it might be because my body clock is set to his nap-inducing lecture style. It's not like I can doze off during other classes, just this one. But seriously, how normal is this? Do I just need to face my fears and power through the lectures without falling asleep, or should I consider getting a note from my doctor saying 'Boring Lectures Syndrome'? What would you guys recommend...?
