Help staying awake!!!?

Question

I'm currently a junior in high school. Its all good, but i have lunch 4th hour and after lunch (5th, 6th, and7th hour) i cant keep my head up. today i literally fell asleep sitting up while i was taking notes. i eat lunch everyday, so i know thats not why.. what could help me stay awake those last couple hours of the day??

Answer 1

Perhaps the problem isn't weather or not you're eating lunch, but what you're eating.  Examine your diet, and perhaps consult the school nurse or a nutritionist to see if that's your problem.

Answer 2

go to your doctor and explain the tiredness, there may be more to it than meats the eye. I use to nod off all the time and i was alway sleepy, turned out i had an underactive thyroid.

It may be nothing but the doctor should be able to put your mind at ease with a few simple tests.
