How long did you take before your first course of antibiotics? Did you catch it in the magic 3-weeks after the bite?
I haven't had it, but I live in fucking Lyme-central in NH. 80% of the deer ticks here test positive for Lymes. It's insane. A good friend got bit and almost immediately had symptoms so her doc put her on doxycycline and she had a bad reaction to that. Fucking crazy.
You need to work with your doc on varying the antibiotics. Also, make sure that you get a good endo because some other friends (a couple that BOTH have it) have gotten their hormones all fucked up because of it.
And to anybody else in the Northeast: ticks are NO FUCKING JOKE. Check your hair, ass-crack, under-balls, underarms once a day in the summer. The ticks need to be in for 24-48 hours and actively feeding for the virus to transmit, but it really easy to get to that point if you aren't paying attention.
