Dude.
When you have a wicked killer migraine that you have to drug yourself into oblivion to stop, the next day when you feel drug-induced wasted, light-headed, dizzy with a rebound headache is NOT the day to also give blood.
Seriously.
Unless of course you feel like spending the rest of the day extremely dizzy as hell.
Learn this lesson thru my experience. :-)
