No, there was no gradual build up of energy, there was nothing, and then there was everything! I was twitching, insane almost, desperate to do anything and everything at once. Raid MC, knit a pair of socks, learn three foreign languages at the same time, watch all of Firefly, chat with friends, write a letter to dear grandmama, study calculus, program my own dungeon, and then I crashed.
It was like hitting a brick wall while rolling down a hill in a garbage can. There was too much energy, and then none at all. Uncontrolled explosions in my system followed by an oxygen vent to finally put them out, and the crew dying a fast and miserable death.
