ye mate same sort off story for me. i did my head in during a moterbike accidant.and after that i wanted to learn to fly. got my class 2 without to much hassle. class 1 was a different story. i had to go and see a bloke called a neuro syciatrist. or how ever you spell that. he had to find out wether i had any perminant damage. i didnt. but my wallet did after he charched me 750 NZ dollars. but now hold a class 1 and a flying job in OZ. and that all happened in the last 4 years
good luck
