I didn't know about sea bands when I was pregnant, but when I became a scuba diver I found out about them and used them constantly. I get very sea sick on small boats. Most dive boats are small boats. Underwater it is calm, but the surface can be murder on an anchored boat. I now fly regularly with sea bands for rough air.
For those that don't know, they are a set of wrist bands with a small bead that goes over your pulse point on each wrist. Set it 2 fingers up the inside of your wrist from your palm. The British rescue sea service uses them constantly. I've even seen them in Wal Mart now. But you can get them at scuba or sport stores.
