I second the ReliefBand. it can be finiky to get it set up right on your wrist, but once you've got it down (assuming it works for you - if I recall it only works for 80% of the population) it's a miracle. I couldn't do boats or small aircraft without it. as Doug said, one of it's best features is you can activate it after you have started to feel sick and get instant relief. you don't have to keep yourself drugged up on the off chance you may start to feel sick.
