Did you switch to something else for the cruise?
Do it. DH and I tried it out and we felt HORRIBLE the next day, never again. I bought ginger capsules from GNC and took those and bought ginger gum also. Read about both here. Our seas were calm so no issues but kept taking capsules anyway. Chewed the gum on choppy speed boat ride to Stingray City on Grand Cayman.
cvswhere did you find ginger gum?
