Go to your regular doc and ask for 24 hr blood pressure monitor. Come back after 24 hrs and get your normal reading and a letter from him stating your bp in normal and only high during visits (WHITE COAT SYNDROME) take the letter to your ame and he will file it with the feds and you never have to worry about your bp when you get your first class. Happened to afriend of mine and it works like a champ.
Good luck
