2nd year of adjuvant Herceptin

Any early stage(1,2 or 3) people are getting or got Herceptin for more than a year? I am just getting panicked for the idea of not getting Herceptin after my one year of Herceptin is over. I had supraclavicular node involvment at the initial diagnosis. What was your oncologist's response when you had asked for a 2nd year of Herceptin? Any response would be appreciated.

thanks,
Julie
