Itchy, itchy, itchy

Currently, it's 12:41.  I can't sleep because I am covered in mystery hives that go from the top of my head to the my toes.  I am hoping to all hope that it is not some early form of PUPPP, which I had for two, crazily itchy weeks after Anja was born.  Kirk thinks it's excercise induced hives as I went for a run today; however, I have been running for 11 years and I have never had hives.  I am wondering if it is the new jeans I bought.   What I do know is that there is no benadryl in the house (very safe in pregnancy) and my hands feel like they are on fire.  I am also sporting some lovely splotches on my face.  Oh, I'm so looking forward to teaching tomorrow, bright and early!
