Yea dude you will be fine!!!

The first couple of flights i went up on i got sick as a dog!

I got discouraged just as you did, but trust me, that feeling will start to pass once you get antiquated with flying. Something that always helped me is to BE SURE TO EAT before you go flying, i know it sounds crazy.....but a full stomach is a more stable stomach.....at least for me!!!

But yea man, dont loose that motivation and let a little puke kill your dreams!
