I have morning nausia without any headaches and there is no possibility of me being pregnant what could it possibily be, what can I do to relieve it?

Reflux? sinus? Could be related to gastroesphageal reflux, stomach inflammation; could be related to inner ear/sinus/position stuff, other. See your doc.
Morning nausea. Gastric reflux is often the cause. You may not exactly have "heartburn" but what and how you eat the night before may be at fault. See your physician . Dietary changes and gastric acid inhibitor such as Prevacid (lansoprazole) may help.
