I know I snore like a bear with sleep apnea, but I have never had the pleasure of snoring my way across the ocean on an overnight BA flight.

My question is "how annoying am I likely to be"? Sure, everyone snores a bit, coughs, and dare I say it breaks wind every now and then, but do I have to steel myself for some gentle rousing from the CSD to warn me I'm disturbing the other passengers, or does the noise of the engine manage to drown out most of the noise?
