Also, if you go to a regular (non-FAA) doctor for medical issues and fail to self-report them on your FAA medical form, it's totally illegal AND you will almost certainly NEVER be found out, unless you stroke out in the cockpit. DON'T hide from the truth--that could kill you stone dead, brother.

Additionally, join AOPA and use their aeromedical help line as a sounding board for your problem. Worth the $35 a year.

So to recap:

1) DON'T wait to go to the doctor, even on the sly.

2) DO apply and interview. Get a job.

3) DO lose weight for yourself and your future. Diabetes, heart probs, stroke, you are DONE flying, even for fun. DON'T WAIT. START NOW. Crossfit and the paleo diet worked for me, but the important thing is to have a plan (get some help if you need it) and execute.
