Endless headache

A funny fact is that the pain transforms me to a superman. I don't need sleep and food. Just 6 hours sleep is enough for me. I become super productive at work. And the work result is flawless. I manage to reconcile with a person I used to dislike very much. I tidy my little place and so willing to wash dishes (the more the merrier). I brought up a tough issue with my manager (I never dare to do so before). A meal for a day. I could stroll 2 miles without feeling tired. I feel I have endless energy. Though I also have an endless headache.
