Are you opposed to herbal treatments? The reason I ask is that it's easier to ramp up on the doses much slower and to reduce doses slightly when herxing, rather than just stopping them.
If you aren't
open to herbals, then I would suggest that you get your detoxing issues figured out so that you can not stop the abx quite so much. There may be one or more of several reasons why you are herxing so much, this article touches on some of them:

Depending on what probiotics you are using now, and what your exact symptoms may be, it could be that the probiotic that you are using now is not the right one to help with what you are going through. Maybe a switch to a better probiotic (one with more strains) would be of more help?
