To help alleviate the nausea you should consider trying a product called Sea Bands. These wristbands have a small snap that can be located over an acupressure point on the wrist. They're sometimes used on cruise ships and for pregnant women to ease nausea. They're not particularly expensive and might be the perfect solution for you.
There are also many home remedies to try for nausea. Flat soda, ginger ale, ginger pills, separating liquids from solids and eating bland foods are just a few options.
