You have a rare but treatable medical condition. Every day, you must take a dose of 1 tablet of medicine A and 1 tablet of medicine B.
If you take the wrong dose, you will get sick. You must be very careful because the tablets look identical.

You are happily enjoying a vacation when bad luck strikes. With 2 days left, you clumsily drop the 4 remaining tablets on the floor and they get mixed up.
You have no way to get more medicine. What can you do?
