Anything besides Dramamine that will help with dizziness after a cruise?

I just got back from a cruise and still feel dizzy and nauseaus sometimes. Apparently Dramamine can help with this (called MDD I found out after a google search), but it makes you drowsy and I'm working. I'd like to stop by the pharmacy on my lunch break and get something but is there anything like Dramamine that won't make me drowsy that will help with these symptoms?
