Darkside, Good to know you were able to tolerate the treatment well. My best wishes for the continued recovery.
In 2020 I was diagnosed with MBC Her2+ in 2020 where one of my lymph node and liver was metastasized.
I took 6 chemo with Taxotere and Herceptin with Perjeta. The scans then showed me completely clear of cancer but i was asked to continue Herceptin and Perjeta every three weeks for life, which i did. It has been 5 years now and I am cancer free according to the doctor. Now I for last one year i am on PHESGO which is an injection mix of Perjeta and Herceptin. I had taken 3 opinions and i was told the same thing. Herceptin and Perjeta for life or till I become immune to it.
I have developed Neuropathy with it and do have body ache and muscle pains. But I am able to live normal life.
So if you are supposed to take it only for 12-16 months, I think that's a very encouraging news. Of course you have to make your own decision. I just thought I could share my long journey of Perjeta and Herceptin with you so it may make you happier to know that you don't need to go through that.

My best wishes to you.
