Congratulations. It's always a relief.
Two years ago when I got a second class after a long hiatus from flying, I sighed a huge breath of relief as I stuck it in my wallet. Little did I know that in a few weeks I'd get a letter from Oklahoma City regarding my CPAP compliance. A three month battle ensued where I was without said medical for several months.
This September when I renewed it again the AME gave me a clean bill of health. Even after that, I kept anticipating a letter from FAA finding something wrong. I finally realized in November I was probably not going to get a letter again.
Sometimes it seems like the FAA doesn't want pilots to mess with.
