Can't believe how real WD is...

I have been taking hydrocodone and vicodin at least 4x a day, sometimes up to 8x a day (to chase the energy high and the "superwoman" feeling...oh, and for pain...), and I took my last one about a day and a half ago and I cannot stop sweating, feeling chills, insanity-provoking restlessness, insomnia, and total lethargy.  I am also due for a surgical procedure next week, so I can't take any ibuporofen OR vitamins.  Help!  What can I do?  I have to teach tomorrow....
