I always used a wind-up timer. I'd set it for the full hour and study. When it went, "ding" I finished what I was in the middle of, set the timer for 10 or 15 (depending on how hungry I was), go pee, have a veggie or fruit (high carb but no refined carbs) snack, then do something totally mindless for the rest of the time.

During finals, if I had to cram, I'd cut the breaks to 5 min sometimes.

12 hrs before exam start, I stopped studying, had a good meal, then slept 8 hrs. This gave me plenty of time to get up, shower, dress, eat a good (mimimum refined carb) breakfast, and make it to the exam.

The reason I stayed away from refined carbs (white sugar, white flour, and syrups especially) is to reduce the crash that comes an hour or two after eating them. It really reduces your grade if you fall asleep during the exam - and the proctor won't wake you unless your snoring bothers the other students.
