I have chronic nausea, but some is from meds, and other is from a tummy condition I deal with. My gastric system empties so slowly that I can only eat tiny meals at one sitting. if not I get a complete backwash of most of my meal for hours. I have woke myself up in the middle of the night some 10 hours after my last meal regurgitating it, and finding a mouth full. GROSS!

Peppermint tea is helpful, as well as nibbling on some dry saltines to absorb the excess acid in your tummy. Ginger is wonderful! They sell it in tablets now, or you can sip ginger ale that has real ginger in it.
