Why do I get nausea every night? Me and my body are getting tired of having to take pepto bismol or Tums (calcium carbonate) to deal with it, just to sleep. : (

Gastritis or GERD. I suspect you may have either gastritis (inflammation of the stomach lining) or gerd (gastroesophageal reflux disease or acid reflux). Diet (caffeine, chocolate, alcohol), tobacco, medications (ibuprofen for example), and infections (h. Pylori) can all be possible causes for the inflammation. I would suggest you see your primary care doctor to discuss symptoms and possible treatment options.
