Tammy, what you describe is exactly what I encountered... my last day of radiation was Dec 4th, about 7 weeks ago. I am not familiar with Miracle mouthwash, but I found that regular rinsing and gargling with salt water helped with the mucus a bit. I still have some mucus, but not near as much as before. It will gradually subside Tammy, and you will find yourself being able to handle soft foods like soup and such. Be patient, take it easy, try more and more small bites of pasta, soft beans, milktoast, well-cooked veggies, etc. Take in plenty of your liquid nourishment too. You might be sensitive to hot/cold food and beverage temps... I have to have everything lukewarm. And don't be surprised if things taste a lot different, or have no taste at all.
