My eyes hurts!

Somehow when aiming and shooting is quite hard, I go spin around and around and it makes me dizzy [@_@ ] and die -_-. And it doesnt goes to the flow when Im aiming, how do I put this...uggghh.... when Im scrolling on it, its too fast. ugh! Im getting dizzy I dont know what Im saying already >.<
