The Cause of My Insufferable Headache

Is it

• Not eating enough?
• Insufficient amount of sleep?
• James Joyces's difficult prose?
• Perpetual process of writing+waiting?
• Overload on school work?
  
• The necessity for days with 28+ hours?
• All of the above?

Too many variables to test out. Scientific method will not work for this experiment. What's that? Minus ten? Scales lie. Gravity lies. Newton lies. Time to warm up a boca burger. Scratch that first bullet off my list.
