Not really. At major airlines there are special programs that help with this (even with DUI's surprisingly) mainly because pilot unions make it part of the contract. For a corporate pilot, there is rarely any recourse. one other thing to remember is that the environment in the aircraft is not very friendly: very low humidity, constant changes in pressure (even if the plane is pressurized). Flying a lot of passengers also means you are exposed to a lot of germs. On top of it all, add constant lack of sleep, sedentary lifestyle, etc. You have to be very proactive to stay healthy.
