How to help my motion sickness?

I'm a college student who takes the bus to school ever day. It's paid for in my tuition %26amp; fees and parking costs $5/day so I pretty much have no choice but to take it. I've always had bad motion sickness on planes, boats and sometimes cars but lately it's become unbearable on this bus. I can't take dramamine even though that's what I usually do because it makes me super drowsy and obviously I don't want to be falling asleep in class. Does anyone know of any non-drowsy medicine or home remedies that can help me?How to help my motion sickness?There is a pressure point used in Reflexology called P6. Look at the anterior side of your arm. If you feel around on your wrist, you will locate two tendons that are about 1/3 inch apart. The pressure point is about 4 finger-breadths above the point where your wrist bends, in between the tendons. You can use either side; it doesn't matter. Hold firm pressure on this point for 20 seconds or so, and you should feel the nausea subsiding. You can do it as many times as you need to.
