Talk to your Dr. about Zofran. It is a fantastic anti-nausea/vomiting med that is given to chemo patients, pregnant women dealing with morning sickness, and anyone having surgery to combat the side effects of anesthesia. It works great!
This little pill has allowed my wife to totally enjoy heading offshore. Before we tried this, she would be sick 100 yards past the jetties. Now, she can handle being out all day and hasn't been sick ever while taking Zofran.
