What must one do when one is sick? What must one not do when one is sick?

Recommendations:

• Must do: Medikamente einnehmen (take medicine), den Arzt holen (get the doctor), viel schlafen (sleep a lot), Honig essen (eat honey), Tee mit Zitrone trinken (drink tea with lemon).
• Must not do: kalte Milch trinken (drink cold milk), in die Schule gehen (go to school), spazieren gehen (go for a walk), Sport treiben (do sports), im Bett bleiben (stay in bed - *Note: This is often recommended, but presented here as something one 'must not do' in the context of the exercise, implying it's a choice to be made if other options are available, or perhaps a misunderstanding in the original text/exercise structure.*)
