Try this trick next time you feel sick to your stomach: Lay flat on your stomach and instead of having the pillow under your head, place it under your stomach (with no pillow under your head). My mother used this technique with me since a very young age and it almost always cured my upset stomach-and it still does today. Other natural remedies for upset stomach are teas made from Chamomile (for cramps and indigestion-avoid if allergic to ragweed), Ginger (for morning sickness or motion sickness) or Peppermint (for irritable bowel, overeating stomach aches). For sea sickness on sailing and boating trips, looking at the horizon helps ease symptoms as does going to the lowest level of the vessel where it doesn't sway as much. And munch on saltine crackers. Don't leave your stomach completely empty.
