Do you ever fall asleep in the cinema? I often do and it really annoys me. It just sort of creeps up on me and there is nothing i can do about it. At home you can get up and walk around or throw water on your face or whatever but at the cinema you can do nothing. Many times I have desperatly tried to stay awake but find myself nodding in and out and then lose whole chunks of the film. Does this happen to anyone else and what can be done about it?
