pezIt's me again... just remembered another thing.
When I was having a drink after my non-blood-giving session, there were a couple of women there also. One of them said that she's had a headache all day, but after giving blood, the headache's gone. And then two other women said they've had the same experience, headaches always go after donating blood. O_O
The ancient art of bloodletting actually works???
[edit] http://science.howstuffworks.com/question648.htm: "Primary headaches can also be caused by too much blood flow. For example, if you have read How Caffeine Works, you know that caffeine reduces blood flow in the brain. Some pain relievers contain caffeine to take advantage of this effect. If you have been taking caffeine every day and you stop, you can get an incredible headache because of the increased blood flow in your brain."
Also read that lowering blood pressure can help reduce headaches. Perhaps that's got to do with it too?
O_O!!!!

And don't EVER ask me to stop drinking coffee like some clueless people keep insisting. I tried once. I thought I was going to die as my head was splitting.
