Flying tomorrow morning (1 hour in air - Edinburgh to Bristol). Claustrophobia gets me about flying not feeling I will crash and die. Doctor a bit vague about when to take the 5mg tablet he has given me (just said 'in the morning') I didn't ask for more details as bit embarrassed I need tablets to fly now as I never used to. Done some online research which says peak strength is 30 - 90 mins after taking. Anyone got any experience about when I should take the tablet i.e before I leave for the airport (30 min trip) at boarding, on plane in seat? Thanks. P.S this is a test run for a long haul flight I will be taking in May .
