If you live in the Northeast or Midwest, unless you spend zero time in the woods (and you shouldn't, because the woods are great), you <i>will</i> get a deer tick on you at some point, and it might carry lyme.<p>My strategy? Go online and illegally buy doxycycline intended for fish tanks. The pills are exactly the same color, shape, and size as what you'd get from a pharmacy. If you find a tick on yourself, remove the tick correctly (do not crush his body), then crush a pill and make a paste, which you should apply topically.<p>If you wait to see a rash, you've waited too long. If you wait until you feel sick a few weeks later, you've waited too long. There are studies that report the rash appears only about half the time, and the blood tests are inaccurate for the first month or so after exposure.
