i snore quite loudly...unfortunately this caused by an elongated soft pallete and unless operated on there is nothing that can be done.
i do get quite anxious when flying so tend to sleep upright in my seat to alleviate any annoyance i may cause.
I have been on several long haul flights where other passengers have elbowed me in the side, smacked the divider, kicked the back of my chair....to wake me.
So thanks for that...i have poor sleep anyway and then its compounded by passengers who dont know how to use the earplugs kindly provided by EVERY airline.
Perhaps a little consideration for those suffer this affliction on a nightly basis..
