thanks so much G-TTIC. its not incapacitating it's just uncomfortable! and it doesnt happen too often but i'm just taking extra precautions. i'm quite a busy person as it is between college work and social life and often have very long days and i can manage, its just the altitude i'm worried about!
I'm also trying to research other side affects of flying that people may have experienced, its probably the ONLY thing im worried about right now hindering my potential to be a hard working excellent CCM!
thanks again!
