How have you been getting them? If you go out a lot, I assume you take a lot.. just asking. I had vertigo and it's how I got them...unless it's a washing machine out there it's not that bad, sick wise for me. Also, 4 patches per box.I wish it worked like that for me.
I couldn't take enough to keep me well. Lol. The patch works great for me tho.
Unless I am mistaken each patch can be used for 3 consecutive days as long as you do not take it off.
I found that the glue that holds the patch on is not good. They come off after showering or if the weather is hot and you perspire a lot. So I put a water proof bandage over the patch to keep it on.
