This has been such an informative list, I would like to ask for any suggestions regarding travel. I am going to Paris in June to complete a class. I have not done time changes, altitude, etc., well. If anyone has suggestions for the airplane air or use of CS as a prophylactic I would be interested to know. Someone said that there was an air machine you could put on your neck in the plane to help not breath the recycled air. thank you, Karen
