your scissors to cut your thread are not allowed, no matter how small, neither are nail clippers. needles--that i am not sure of(at least that was what i was told)

and then for the motion sickness, dramamine is the best. what i did was took a dose of it 30min before take off so it have a chance to work. then i made sure that the cold air vent was pointed at my face so it felt like i was breathing fresh air. and you can either look out the window, or shut it providing that you have a window seat. if not, close your eyes and concentrate on breathing the cool air. otherwise, makesure that you have a barf bag near

hope that helps and good luck on your flight, keep us posted on how things go!
