Are you taking injections? If so, you may need to call the airport ahead of time to ask about getting your syringes through airport security. I haven't flown or traveled much since my ms diagnosis, but if I were to go on a trip, I would try to make sure that I made the trip as easy on myself as possible by arriving at the airports early so that I wouldn't have to rush. When people tell me "we all get tired" i just say "well I get extra tired and need a break before I crash". I've learned that straining myself too much flairs up my symptoms, and that sometimes I just have to tell people that I need to rest. Your health comes first, and that is important to remember. Good luck with the trip! Don't forget to call about the needles if you use them.
