Hey Pauline,
Sounds like you have your own brand of "air pollution" going on with Lewy!
I know how bad it can get. During my mom's last couple of weeks all her waste of all kinds were rank beyond description. Sometimes I thought we would have to evacuate the building, or call a haz mat team! It's not everybody that can clean up this kind of "pollution!"
I took it to mean that nothing in her body was functioning properly anymore, and that organs were out of balance and were slowly shutting down. Lewy's kidneys might well be failing, one day at a time.
Thank goodness it is spring and you can throw all the windows open and run the fans! Those odors are extremely persistent, but at least all this helps!
Get out of the house at every opportunity and breath some fresh clean air and smell every nice spring flower you can find! These situations do give us an entirely new appreciation for breathable air! (You might consider going to an army surplus store and buying a gas mask! Who would Lewy think you were if he saw you in one of those???)
Love you,
Patty :)
