I have a migraine.
Two things happen when I have a migraine. My vision goes, and I get a delightful shimmery effect on my sight. (I am typing this by lifting my chin up so my undisturbed optical nerve can see). It is called an aura, and it affects the same part of the brain as schizophrenics and their visions. Just goes to show how strange the brain is.
Secondly, I feel the need to tell every one about it. Lucky people you.
I’ll keep going till lunch and if I don’t feel any better then I’ll go home and crash. Blurgh.
