hey there, when i got dx'd i was days away from a 2-semester trip to study in australia. i was getting last minute health check-ups that led to my dx. (i also had an accident on a snowboard that seemed to precipitate my dx attack).
on the day before leaving i had to make the final call, and decided to postpone my trip. at the time i did not know when the progression of problems would slow. it was too scary. my bon voyage party turned into a non-voyage party.
i recovered enough (barely) to make the trip for the second semester. it was rough. luckily i had had trip cancellation insurance, and still i did have to wait for three months of stable health, in order to purchase 'pre-existing condition insurance'. it cost me 600 CDN extra because i was going away for months.
the trip was rough because the flights were long to get from SW ontario to western australia. at that point i was still paying others to wash my hair for me.
anyway i gradually got better over my time there, although i've learned much more since i returned in late '06.
at the end of the day, yes there are risks in travelling but you can manage if you are determined. i was fortunate not to require emergency care overseas. if you think you will, i guess i would advise caution.
in the final analysis, it is all up to you - all i can provide is one experience
