Replying to Air sickness

So I'm leaving for Windells Friday morning. My flight is at 6:45 a.m. I'm flying Southwest Airlines (never have before) and I have a connecting flight in Denver. I usually fly Delta which uses larger planes and doesn't usually have connections. My problem is air sickness (turbulence). Southwest uses small commuter planes for connecting flights which turbulence affects more than larger commercial jets. To get to the point, I get sick real easily on bumpy flights and was wondering if any of you guys have advice or tips that could help. +k to good responses. Sorry for the long explanation. Thanks.
