Avelox and yeast infections

I've been on Avelox for just two days of a five day prescription, for bronchitis. Only side effect I've noticed is increased, uncomfortable-to-painful bowel movements; this is to be expected, though, because a strong antibiotic gets rid of ALL bacteria, the good and the bad, and the intestines are infested with the stuff. This also the reason many women (myself included) get yeast infections from taking antibiotics.

Maybe I'm not having as hard a time because I drink 2 liters of water per day, work out regularly, and take vitamins and supplements with every meal.....? Perhaps it's because the newer antibiotics - Avelox, Augmentin, Cefalexin, Cipro - are simply too much for some people's systems to take....? If I were aged, obese, on medication for other health issues, or were otherwise in less than optimal health, I'd might be having a much worse time of it now.
