The individual's degree of agility is why some remedies work well for some but not others.
One theory is the brain assumes that the cause of the stimuli mis-match is due to ingesting poison, and reacts by signaling the stomach to eliminate it by hurling.
And this is why one feels better after spewing his guts.
Ive found that some find relief from sea sickness
by dulling their senses with certain medications, and some find relief by soothing their stomachs. Ginger seems address both for me, ginger ale, ginger snaps, ginger tea, and Ginger the movie
