Sometimes I would go three days with no sleep of any kind. My brain
scaned information sort of like the desktop of a windows PC filled with houndreds of folders. i would try to play out, repair, rethink, solve, and fix every issue of that day, the day before, and the day to come, all at the same time. This not only caused the severe insomnia, but when a major issue did pop up.... tight chest, cant breath, tingling in fingers, chest pain, tunnel vision, weakness in my left arm, and exaustion.
