Me eye and head is suffering!

I have been staring at the computer for 12 hrs almost daily!... After learning autocad for ~ 3 weeks, I am now doing programing using Excel. After work, I watch TV and sailormoon videos.. Plus upkeep of my blog. Shess.. my eye seems to be straining too much.. My head is like bursting, cos the I keep looping the excel eqn until so complicated. Now i dun even know what I am doing.. I got a date to complete... Shess... My tag board and counter are not working... I want to change my scroll bar to yellow... I want to chnage my music as it does not auto play! But only way to do it is to upload songs into geocity and the only way is to sign up with them.. So mafan.. I still haven got to it yet. But I really like my skin now. Bright and cheery! I really think my eyesight has increased... I am around having a degree of 600 plus for each eye !! Time for lasek... hoho..
