Congratulations, Cppoly!!!
I don't know much about
the abx other than to tell you to be sure to only start one at a time and if it gives you any issues, stop and try a lower dose and build up to the dose that is prescribed.
If at any time the abx start to bother your stomach, be sure to eat something just before taking them.
As MrsPallas said - be sure to take lots of probiotics!!!
It sounds like you are in good hands!! May you heal well!!
