Hrmm.. i pulled close to 200 in '03 ....but that was when i lived a 'faster' lifestyle... my brain is probally worse for the wear, but the hallucinations were amazing and terrifying at the same time... it was just the voices that got rather draining and disturbing.... i think sleep keeps the frequency of conciousness slightly offset from the absolute frequency of this reality, too long awake and you start to synch up with things you dont want to know are there...
