Looks like the nausea diagnosis was right. This morning's ondansetron didn't seem to do enough though. She slept a lot, ate during the day when I offered it but at PMPS she refused all food, even the Tiny Tiger. Had a little sardine then walked away. Got a second ondansetron in her tonight, then pulled out the ad which she ate and then had most of her dinner (which had the potassium and boulardii and spironolactone mixed in). Diarrhea again tonight. Sigh. Then I remembered it's a holiday weekend! Always a good trigger for random illness.
