Girls, help?? The problem is that I ate dinner yesterday, woke up at night and felt like something was sliding down my throat, in the end it started with rotten regurgitation, as if something was wandering around in my stomach. In the morning I threw up everything I ate for dinner. Throughout the day I drank sweet tea, chamomile and a few cookies. Again, this regurgitation started, then vomiting followed. At the consultation and examination by a gastroenterologist, there was gastritis, but no other digestive system diseases. Do you have any experience with this? How did you cope? My doctor says to drink Mezim, it doesn't help. Hungry all day...
