I wouldnt use anitbiotics for test flu, if that is in fact what you have. The "real" flue seems to be going around my part of the country lately. I had all the basic flu like symptoms and it sucked. I didnt know what the deal was, but I do know it was my first shot. Stay hydrated and pop an asprin. rest up and take it slow till you get better. The aches and pains are soonto be gone and youll be back to normal. That is, if it is test flu and not AIDS. Good luck!
