But there are several cases where the student airman didn't know that his history of SSRI use, or ADD/ADHD diagnosis as a kid, or 2 arrests for alcohol related items were a derailment. Lots of money spent on training to find out that either he is forced to abandon the dream, or spend lots more time and out of pocket money satisfying the FAA's requests for info and documentations.
Or you could pursue a Sport Pilot certificate, use your driver's license for a med cert, and not hassle with all that. Or fly sport for a while and do the medical hassle later. BUT, if you do the med and get denied, that option goes away. Choose wisely.
I'm working on my sport ticket not for medical reasons but because it covers the type of flying I plan to do and I'm more likely to finish than if I bit off Private all at once. I might upgrade after flying sport for a year or two, or I might decide there's no need. At least for the first year or two, daytime VFR in a simple plane with one passenger will be plenty.
