I am 2.5 months out from treatment, and can pretty much do anything I want. My current "issues" are dry mouth, neck and shoulder stiffness, some neck tenderness and episodic swelling (lymphedema). My taste has started to come back. If it never gets any better, I could live with it.
I am a firm believer that mental attitude is as critical to the recovery period as it is during treatment. I will admit to some depression/anger/edginess since completing treatment, which apparently is fairly common. We burn up a lot of emotional energy during treatment, and there is a natural letdown afterward. I need to really focus on my attitude, and find I feel better physically when I can get myself moving and active.
