hi martha's vineyard, sounds like you've been through quite a lot.... if you're interested in a more "herbal" approach, check out the cowden protocol.
you can google it.... these herbs are produced by www.nutramedix.com ... they make excellent herbal tinctures that really help with lyme. i've had very good success with them, especially for the brain fog thing. everyone is different, but it's definitely worth looking into. a very prominent lyme doctor recommends using these tinctures for those who have done abx treatments. they also help detox the sytem as well as treat the micro organisims....
worth checking out.... i can vouche for them..... good luck....
