Motion Sickness
"I have used meclizine on cruises and boat trips as I am susceptible to sea sickness in moderately rough waters or worse.  Although it makes me a little sleepy, it&#039;s not so bad that it affects what I do.  It just makes it a little hard to get up in the morning- takes me a little longer to feel &quot;awake&quot;.  Otherwise, I usually feel very good with no nausea.  



I used it on a *very* rough boat ride once and although I never threw up, I was nauseous for the last half of the trip.  However, considering how sick others were, I felt it was still helping me quite a bit."
