My elderly father has to take pills twice a day, and frequently forgets to take them. What he doesn’t forget are routines that he has been doing for all of his adult life. Is it worth me establishing a habit of taking no-effect sugar-pills twice a day from a marked container, so that if I get into that state the pill-taking habit will be thoroughly engrained by then, and I (or a weekly helper) can just substitute real pills for the sugar pills?
Given the evidence in my family: no good whatsoever!
