I can go all weekend without caffeine and not get a caffeine withdrawal headache. (I don't always go all weekend without caffeine, partly because James is getting much better at making a good pot of coffee... meaning it has neither chunks nor the approximate pH of battery acid.)
If I'm at work and don't have caffeine by 9:30, I've got the caffeine headache.
Yes, fun with situational learning.

Strobe lights of any sort (read: disco lights, computer monitors, and flourescent lights) have a 'refresh rate' that means they aren't on 100% of the time.
The average user can't see the refreshing of monitors and/or flourescent lights. The person with sensativity to them may or may not "see" the refresh rate - but is still vulnerable to it.
In epileptics, it can cause seizures - in sensative folk, optic headached or migraine (both 'clinical migraines' and 'migraine headaches')
Hence why things like Excedrin have caffeine in them.
Since you are without your coffee AND in an environment where the lights go flashy-flashy... headache comes on sooner!
Did that make sense?
