You worry more if your medicine is FAA approved than FDA approved.
It seems perfectly reasonable to drive an hour to an airport to fly 40 minutes to a restaurant to have a "quick bite to eat", and then fly back to the airport and drive back home for a total cost of 3.5 hours of total travel time and $200 in airplane rental fees. When it would have taken only 1.5 hours total travel time and no airplane rental fees to drive to the same restaurant directly from your house.
You are very careful to not drive drunk because a DUI arrest will make renewing your medical problematic.
