Just got back on the 9th and rough seas our last day. Ginger was my best friend! I took it the whole trip but didn't take it on time the last day... Turned green with motion sickness. Took my Ginger and in 30 min. I was great again!!! I've tried other things and they didn't work that well!!! If you are cruising soon be sure you pick some up!!! No side effects as with the medicines!!!! Happy sailing!!
