too much brain activity?

Hi my friends! Things are going good. I am really nervous now and willing to do my best, everything else can wait or go to hell! And the past two days have been really good, I've written some pages and have been working really intensively. It's like my brain is doped! and I read everything fast, am very concentrated, think clearly... but almost too much... I'm kind of hysterical, actually, can only thinkg about the problem I'm writing about, etc. That is all fine, since it's just one month now. However, I have had a headache all day today. It feels like it's really coming from too much brain activity... every bit of info is dancing around in my head and connecting with the other bits in many different patterns... So I think I should try to relax a little bit, because there is a point where I'm too hysterical to be writing the arguments step by step and would like to just do everything simultaneously. That and the headache...
Do you remember the movie Pi? I'm not a mathematical genius trying to think the name of God, but it feels remotely like that...
