Hi, My Name Is Rudy. I Wear The Patch Because

Hi, my name is Rudy. I wear the patch because I get nausea every 2 days because of my stroke I had in 2012. Is this patch worn forever or will I get rid of it? Is there an alternative to the patch? Do you suggest that I change ears when I apply it. Is there a way to cut the cost. They are very expensive.
