Good stuff ^
I'm adding ear plugs to my gear. Great idea.

I would also suggest considering Ginger to combat/cure motion sickness instead of other meds.

Ginger is a natural anti-nausea substance, and in my and my crew's experience, has no unpleasant side effects like drowsiness, dry mouth, etc. I urge my crew to take a Ginger pill, regardless of their history with motion sickness, on travel day, when we step on the boat for the sleep aboard, and again in the morning as insurance against fun-killing motion sickness. After that, only if they think they need it.

On our first trip to the ilons, the folks that were worried about motion sickness used the patch with mixed results/experiences. Since then, they've used Ginger and have been much happier.
