Sending me up the wall

Would walking on the walls and ceiling make you sick? Not mentally, although if you thought you were than you probably are...sick that is, not walking on the walls. What I mean is, could your brain cope with seeing everyday objects the wrong way round? Would this happen during the transition from floor to wall, or would it take a little time? Maybe different people are affected differently. Personally, I can't stand spinning upside down on rides, so I probably couldn't hack it. But, given the chance I'd give it a go.
