This happened to a friend of mine's dad. He hadn't flown in years and got a DUI sometime a long time ago. He was interested in beginning flying again and knew he had to report the occurrence at some point. He did the right thing and reported it, and pleaded his case. They still suspended his certificate for a few days. It didn't really affect him since he doesn't fly for a living, but it sounds like the feds aren't too understanding in this case.
