Motion Sickness Medication/Breastfeeding

Hello ladies! I was wondering do you guys know of any motion sickness medication or anything used to combat motion sickness that is safe for breastfeeding mothers. I still breastfeed my eight-month old daughter (who I will be away from the FIRST TIME EVER, I'm so sad 😢😓😡) so I really need the medication to be safe. My husband and I are going on a weekend cruise for our two-year anniversary and I'm worried I may have motion sickness. I haven't been on a cruise since college (it's been a few years) and I remember suffering through motion sickness then. Thanks in advance.
