Reddit mentions of Urban Moonshine Calm Tummy Digestive Bitters | Organic Herbal Supplement for Occasional Nausea & Upset Stomach | Chamomile & Ginger | 2 FL OZ (Pack of 1)

Some non-meds things that have helped me a whole lot:

• getting a full length foam wedge for under my mattress (like so, pricy but a one time expense and so worth it for me)
  
• making my meals much smaller and more frequent and stopping at the first sign of any discomfort (you can always try again later)
  
• taking smaller bites of food and chewing for a longer time
  
• keeping something minty around and/or drinking peppermint tea a lot or gingery things if you like them (I'm more partial to the coolness of mint)
  
• making sure I drink a lot of fluids and electrolytes (but in small frequent sips, I try not to chug liquids)
  *making sure I get exercise of some sort at least a couple times a week (I try to move around after I eat too, even just a short walk)
  
• digestive bitters like this, this or even some digestif liquors/liqueurs like Fernet-Branca, Branca-Menta, Underberg, various Amaros, Campari, and so forth. Here is some neat research from NIH on bitters: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4446506/ (ctrl+F digestion if you want but it's not very long and pretty informative).
  
  I hope any of these things helps. I also work with my gastro doc and my primary and use medical cannabis, but ultimately for me the biggest improvements have come with the lifestyle adjustments above. I wish you the best of luck!
