Anti-Nausea Medications & Natural Remedies for Nausea

Hi, I have a fairly weak stomach (GERD, motion sickness, random days of nausea and gag reflexes).  I'll be on a 6 hour flight in a week and want to avoid getting air sickness due to my stomach conditions.  Just wondering whether anyone can suggest any reliable anti-nausea medications and natural remedies to relieve the nausea?  Thank you for any of your input.

Ginger ale, milk, and peppermints are good for tummy indigestion.  You can take motion sickness pills from the drugstore, too.  I have a relative who always gets sick on the plane, so she takes those pills, meclazine is in it, I think.  Sit next to a window if you can, if it's clear out, you can focus your gaze on the horizon and it'll help a little.

I know ginger usually works very well for nausea, even ginger mints. There is an over the counter medicine called Gravinate/Gravol that works well also.
