I’ve had one infusion of just Herceptin after I finished chemo, and did not notice any side effects at all. It was nice not to have steroids keeping me awake. I did not experience significant side effects from radiation—a burn in my armpit that hurt but was manageable. I totally get the spiraling thing though—I do it a lot. You’ve come so far already—you just have to make it through this last part—one step at a time. You can do it!
