Now the pain is gone and I feel rather hung over. Unfortunately, I'm out of medicine too but I'll call my GP tomorrow. I surfed the web a bit to read more about the causes of migraine and I found the english wikipedia entry very helpful. I also found a description of the medicine I take very interesting. According to what I read, my brain has problems with serotonin and here is a picture of my hero:
Sumatriptan
If you have headaches and do not now how to deal with them make an appointment with your GP. My live changed drastically when I got the new medicine. Before that I would be trying to get some sleep while trying to ignore the pain and the nausea probably for the whole night. Now I slept for two hours, ate supper and I'm pain free. There is nothing to lose!
