I do this every other sleeping period...

I will be up anywhere from 24 - 48 hours and then sleep for 5 or 6... when I wake up it is about 12 hours before I am tired again so I sleep, usually about 8 hours... when i wake up from that the cycle starts over again...

No drugs, except some coffee in the morning, but not a lot.

During the day I feel sort of a barrier being breached when a normal person would feel like sleeping but if I don't sleep at that exact moment then I will be up for the whole next day with a sort of awareness that I really can't describe other than a high alertness...
