I've had one, and you should definitely take it easy. I really had a hard time just taking care of life for a while after mine. I had bouts of extreme dizziness and nausea, and mild confusion. The confusion would have been enough to cause an accident, or mess up something at work. I did drive the day after mine, but I shouldn't have. I was too dizzy and disoriented. Light was painful, as was sound, and both were disorienting.
I'm sorry this happened, but you do need to take the day off and sleep in a dark room. :(
