My side effects were bad. The first 2 weeks were okay, and after that it went downhill. Sores in my mouth, difficulty swallowing and eating, everything tasted bad, loss of appetite, thickening of the saliva and then loss of saliva (which I have never gotten back), exhaustion, secretions in the throat that lasted long after the radiation ended. But, it does get better and you do heal. A year ago now I was in the middle or radiation, and I can't believe how good everything is now.
