Do ask for specific instructions if you choose the patch, as it does have side effects and you don't want too much in your system. Where your cabin is is very important. A ship nurse told me (AFTER we were onboard and I was really sick) that you want your cabin to be mid ship. Neither end, nor too low. She said there is less motion there. Also advised me to stay out of the cabin as much as possible. Be outside whenever you can.She also suggested taking the patch off after you were on the boat for 24 hours. (I was too late for that) Good Luck!

The patch doesn't make me sleepy, just a bit mellow. The worst side effect is how dried out it makes you. But believe me, I was able to get in a small sailboat in Boston Harbor and have no motion sickness for hours which is a miracle to me.
