Boat Back Ache If You Have Motion Sickness When In A Car, Will You Get Sea Sick On A Cruise Boat?

If you have motion sickness when in a car, will you get sea sick on a cruise boat? - boat back ache

I'm going on a cruise soon and I'm really worried because I sometimes get dizzy in the car. I've never thrown against him, but I have a massive stomach ache. I do not feel sick rides for amusement parks, but still. Please help !!!!!
