Sorry that happened to you. I suffer from acid reflux. If the heart burn is that bad the doc can recommend some medicine you can take while pregnant. If you don't want to do the medicine you can always eat slow, prop your mattress up a few inches so your chest is elevated, don't drink when you eat and eat at least 4hrs before bed. Tums will cure it for a little while but I would definitely call the doc if you're throwing up. Good luck!
