So apparently it's my turn in the hospital now...

[Inquisitive Raven]

The nursing staff are glad that I'm counteracting the antibiotics by drinking plenty of probiotic yogurt-drinks. 

Okay, repeat after me, "Fermented foods good, probioitic supplements bad." I kid you not, studies have shown that taking probiotic supplements doubles the time it takes for your gut microbiome to recover from antibiotics. Stuff like kombucha, organic apple cider vinegar with the "mother" in, and unpasteurized sauerkraut will do you more good than supplements. I'm not sure where commercial yogurt and kefir fit in. I'd bet that homemade is better though. The issue seems to be that the supplements overload a few strains of bacteria which does not make for a balanced gut ecology.
