Thanks, Alicia! I guess that I took for granted that only the 500 mg ginger tablets/capsules are available. So, with the concentrated (1000 mg) tablets or capsules, you would only need to take one tablet or capsule three times a day, starting two days before boarding, and continuing through the end of the voyage.
I kinda like the ginger candy, not because it can replace the tablets or capsules, but because I find it settles a queasy stomach just because of its flavor. The quantity of ginger in them is not nearly enough for the prophylaxis of motion sickness...but they taste pretty good, to me.
Have a great, fun-filled cruise!
