"I live vicariously through myself."
Here's what I can tell you. You won't have to worry about having to puke your way through a job you aren't crazy about. You won't make it through primary flight training if you are unable to get over air sickness. Over my 3 years instructing primary, I saw a lot of airsick students. Most get over it, some take longer than others. The ones who don't get over it are attrited. Your chances of redesignation because of attrition due to a circumstance outside of your control are a lot better than if you DOR. My advice to you would be to stick with it. You've been given the opportunity of a lifetime. If you get over your airsickness, you'll probably start to enjoy flying. If you don't, you'll be in a better position to stay in the navy in some capacity. Good luck.
