I believe the first choice at this point is
doxycycline, with an alternative of amoxicillin for those who shouldn't take doxy. I think Ceftin is sometimes used with later stages.
I took a week of Augmentin 875, a fairly strong penicillin, when I got my initial onset. I didn't know what I had, but I felt a whole lot better with the meds and seemed to recover. Of course that was insufficient... If I had taken a month's worth, I probably would have been okay.
