motion sickness
"As someone who gets sick looking at water and rides that go around and around this patch was a great for my 1st cruise. The boat swayed and I felt nothing. 36 hours after the patch was removed, after using it for 8 days, switching out a new one after 4 days, I feel horrid. My nausea is constant and I am on day 3 of the patch being removed, I am also suffering from severe exhaustion. I had blurred vision, but that was much better to deal with than motion sickness. Will I use it again....not sure. I have not thrown up and I don't have severe headaches so maybe the end justifies the means."
