I have started rotating antibiotics on a semi-weekly basis and I find when I start/switch the new antibiotic I have some gas issues for 2 or 3 days with bms.

Why did you stop the augmentum if it was working?

I got a awful yeast infection

Have you tried going back on Xifaxan since you are having good bms?

Yes, very angry gas, nauseau, burping, xifaxan not cutting it. Started augugmentum again. 

Not sure how to deal with this yeast situation. I guess it will take a few days to work if it does. If not my options r not looking good.

There are a number of choices for treating yeast infections. If you can find one that works (and you tolerate long term) then maybe it should just be part of your antibiotic regimen?

I have found in the past that rotating onto xifaxin helped me conquer yeast infections for the simple reason that xifaxin stays in the gut and is not systemically absorbed.  The other antibiotics that are systemically absorbed over time will kill enough bacteria in other parts of your body that the yeast will opportunistically overpopulate in those areas formerly occupied by bacteria.  Taking xifaxin allows the bacteria count to recover outside of your gut. I primarily got bad yeast infections on my skin (legpits and armpits), and learned to keep them at bay by rotating onto xifaxin, using very good drying hygiene after showers, and liberally applying antifungal powder on any area that started itching or looking red.  This protocol has eliminated recurrence of yeast infections in the past few years.  I did get a really bad one in 2010 and again in 2011 and diflucan was necessary to knock them out.  But none since then while using the above protocol, which is really just common sense.
