I hadn't thrown up for about five years until a few weeks ago. This has made me so insecure since I too have a dreaded fear of vomiting. Ever since then I haven't been able to eat or sleep well. I have a very slight gagging sensation in the back of my throat like a burp that won't come out. I do recommend sodium bicarbonate (basically baking soda). This helps with burping and there is a good chance that you just have trapped gas. Just add a few tsp. In 8oz of water. It might not taste good but it helps and has helped my dad a lot. This for me might effect my personal health and I might go into the hospital from extreme weight loss. If burping doesn't work also try Sudafed. You might just have mucus stuck in your throat. If nothing works, try aromatherapy. Use the essential oils. The oil digestzen by doTERRA usually helps if you place it on your throat. Please be healthy and if nothing works just be strong and power through it! I hope this helps ❤
