I forgot to add I also had strange vision problems too. I work at a computer all day, and text on the screen grew blurry even though I have good vision normally. I thought it was due to the lack of sleep, but after hearing other's accounts, it was probably purely lyme related.
From what I've heard also, the sooner you're started on an appropriate antibiotic, the better chance of full recovery.
I am concerned that having been misdiagnosed for about a year, that there was some permanent damage to my brain, but time will tell. Unfortunately, the only treatment seems to be antibiotics. If you have a really bad case of lyme, they may put you on an antibiotic IV directly.
There are some "natural" medicine alternatives, but there's no scientific evidence of them actually working. It seems like "hogwash" to me, though a surprising number of people swear by them.
