Etichs debate on computers and work vs. me the overnight shift manager?

I work for a large company and my full time job is Overnight Manager. From the hours of 2am untill 7am I have nothing to do meaning all of my paper work is done and all of my duties are done. Recently the company has been blocking websites like no ones buisness such as (but not limited to) youtube, myspace, facebook, quicksilverscreen.com, 56.com, yahoo games, ign.com I dont want to send an email to the companys IS department asking them to unblock those sites because I dont want them saying "well you apparently need more things to do to keep you occupied" and I dont have access to the Admin pwords. My question is should I just forget this all together? If so do you have any ideas on how to keep myself occupied during this time? Also I cannot bring media devices to work either...honestly thats an obvious. p.s I looked for a catagory in Y?A and couldnt find a subject under ethics thats why Im posting it here.
