I stopped radiation two weeks ago and the only side effects I have are fatigue, taste, and the need to constantly spit. I found sleeping with two pillows helps at night (keep head propped), sleeping with a humidifier, and rinsing my mouth with club soda helps. I go through a lot of club soda especially first thing in the morning. I haven't figured out if Mucinex works for me. I take it on the rare days I'll be out of the house and can't freely spit. It is slowly getting better.
