You could ask to go on Ondansetron, otherwise known as zofran. It is a wafer that dissolves on your tongue. It is great but really expensive. A box of 12 costs about $120.

Can I just say I am feeling your pain. I'm 6w6d and so sick! DD is all over me. I have heard good things about sea sickness bracelets. Was gonna go get one today but DH has my wallet in his car. The zofran also made me really constipated last time to so I am gonna try to avoid it this time.
