Just stay in the lab for 30 hours straight and all the symptoms should clear right up....
Seriously though.. I know what you mean. It's that nasty gross feeling that you have, where you can't even concentrate on the simplilest task, becuase you are thinking about how badly you feel, and that you have all thhis stuff to do, so you can't go home.
Honestly.. go home, get some rest. You will be better for it in the long run. It will suck short term, but you can catch up when you feel better.
