Sleeping in Public Spaces

On my routine Tuesday and Thursday, I have this wonderful break for almost 3 hours. I have taken the best of care with this time by doing planning for classes, catching up on emails, filling out forms, reading, researching, etc. But for some reason this lovely 3 hours has turned into to a lazy, struggle. I have spent more time trying not to fall asleep reading my book on the school´s outside bench, downstairs couch, and  sitting at a computer screen in the computer lab. The special lullabye of computers and lights humming is winning. 
In Santiago, during these hours after lunch, this is actually totally normal unless you are on a bus or metro where this snooze is totally acceptable and impresive at all times of the day. Possibly I´m becoming Chilean or maybe just old and tired, no it can´t be it, not either. I need a nap... I need some inspirition, maybe Martha can help or some inspirational videos on youtube, possibly I should eat less so then at least I´m constantly bother by the grubble in my stomach...any suggestions?! Oh thank goodness, the head computer man, George just put on some Spanish rap; this will help without a doubt. He must have caught me dozing :)
