motion sickness
"Used the patch while on a trip overseas, where I would be on a boat, and also being driven around.  I get sea sick and car sick.  This worked well for the most part, but had blurry vision and light sensitivity. I did have the patch fall off a few times while showering, and replaced them right away.  I used this for a 14 day trip.  I stopped after the area became irritated, on day 10, and the area is still slightly swollen."
