zosyn (which by the way i LOVE because it does a great job killing my bugs and it doesn't require lab draws to check levels like tobra) makes me feel like i will never be hungry again when i first start it. that feeling usually goes away after a few days, though. diarrhea and yeast are also pretty much givens, although i was able to keep my yeast down this last time with probiotics. the 6-hour schedule is a bummer for sure, but overall i'm glad to do it because of the results.
