I ate alarge portion of spaghetti and went to lay down. I experienced air bubbles coming up in asophagis. and some feeling of fullness while it was digesting. felt some acid. but I was on my side and felt for justa second like I it was hard to breathe or breathe in deeply and then it passed thinking it was from having air in my stomach coming up and acid and laying down after a big amount of food. think it all was related to kind of food and acid indigestion. pretty sure
