Thanks piper girl, i'll bear that in mind. i did use a preventative for a year but it had no effect on my lung function. i've got nothing to lose however by using one long term though.
i was wondering if anyone had experience of exceptions to the rule/restricted med cats given by JAR. On speaking to a CAA respiratory specialist several years ago, i was told a reason why the regs are so harsh are the possibility of an asthma attack brought on by an explosive decompression at 36000ft. My answer to that was 'how about a med cat that restricts to unpressurised cabins' ie helos. I didn't get a sensible answer. I'd love to hear from someone who has.
thanks
