Hi Dh,
I would heavily suggest that you start detoxing right away to help combat the large amount of toxins that are being released into your system with those abx. We have a great post all about
detoxing when a person has tick-borne infections in our "New to Lyme? Start here!" thread at the top of the forum. You should do all the detoxing that you can - the soaks, the dry skin brushing, and drinking at least 2 quarts of pure water each day. If you aren't experiencing muscle spasms/cramps/twitches then add lemon to the water as it helps to bring the body back to an alkaline state - one the bacteria don't do so well in!
That thread also has a lot of really great info and links that will come in handy as you go through treatment.
Please be sure that you are taking your probiotics at least 2 hours away from the abx - preferably 2 hours afterwards - as that way the probiotics will have a chance to repopulate your intestines with the good bacteria that it's carrying.
And of course, keep asking questions!!!
