Consider Dramamine; downgrading to iOS 6 is no longer an option

"After upgrading Apple devices to the latest operating system, iOS 7, users have reported feeling physically ill because of navigation animations.
A number of users have taken to Apple forums to complain about the new OS update, saying that zoom and motion effects have resulted in nausea, headaches, hurting eyes, dizziness and motion sickness.
One user associated animations with car sickness, and others -- after using their Apple mobile devices for no more than a few minutes and feeling sick as a result -- chose to downgrade their operating systems."
