I had just gotten off my 7th 12 hour shift and hadnt been sleeping good. Got back into town off the bus, felt tired but nothin bad, jumped in my jeep went to town for a bottle of water at the gas station. At some point fell asleep goin over the freeway overpass 25 mph, next thing I'm waking up to is crashing into a crosswalk pole on the driver side minor damage, then slammed into a metal light post on passenger side which dealt the fatal blow.
