Freeze a big cookup and keep in the freezer for when you have chemotherapy, and are not feeling well. Ignore housecleaning – spend your days doing stuff you enjoy. If the housecleaning is too much employ domestic help, or ask family or friends to assist.
Medication
Ask the pharmacist for an information sheet about any new medication, and whether there are any glaring contra-indications it would be helpful for you to know about.
