I did the same thing really bad on Friday night. Fighting leaving the coffee shop even though I knew I was exausted and had to get up at a reasonable hour. Got home, couldn't sleep because of the coffee, computer was fried, couldn't get online, so I got in my own head and had a panic attack, had to call a friend at 4am, got like 3 hours of sleep and was up all day Saturday....I kinda like the goofy feeling....bad, bad bad haha.
