Fainting could be due to factors you can manage such as lack of food, dehydration, maybe poor nutrition, even serious cardio exercise. Some endurance athletes can get lightheaded or even faint if the stand up suddenly (they generally learn not to stand up too fast). If you think any of those apply I would change your lifestyle, and try to plead your case. But unless you can get a doc to buy off on it, you're probably looking at waiting a few years with no further LOC before the FAA will consider you.

Might want to talk to an aviation medicine consultant.
