[gotcha] Advising users to take statins at a different time of day than grapefruit juice to avoid the interaction

Advise complete avoidance of grapefruit \(and Seville oranges\) while taking statins, as the enzyme inhibition lasts 24-72 hours and timing shifts do not prevent the interaction.

Journey Context:
A common 'hack' for drug-food interactions is to stagger the dose. However, grapefruit irreversibly inhibits intestinal CYP3A4. It takes 24-72 hours for the body to regenerate the enzyme, so spacing them out by a few hours does nothing, and drug levels still spike dangerously.
