Alas! I have been struck by Baba Yaga's Revenge (the Russian version of Montezuma's revenge). Mom had a milder version yesterday, and mine hit just as we started our day at the Musee d'Orangerie. Between that and the Louvre and a bit of walking around, my day was marked by repeated trips to the various bathrooms in both museums and around town.
As such, I'm tucking in for the night with the hopes of waking up tomorrow in a fitter state.
