I'm headed on my first ever cruise next month. I am prone to motion sickness (nausea but not vomiting) in the backseat of a car. I do not feel sick on boats BUT I do get the sensation of movement at bedtime after I've been on a boat. The land legs issue is my big concern. I have read a lot about sea sickness medicine options, but I don't know if I should just resign myself to taking Bonine proactively and risk being groggy and unable to drink, or just see what happens with this first cruise? I drink moderately, but was looking forward to a couple of mixology classes. I bought Bonine yesterday and was thinking about a test run to see how I feel using it at home. Suggestions?
