I had a good result with Enhertu. My tumors got smaller and I believe one went away. My doctor was going to keep me on for 6 months but I elected for another 3 months, so 9 months total. What I liked about it was that it was predictable. I was able to play pickleball by about day 12, took walks everyday, though I was tired before about day 10 or so. After my last infusion I thought maybe I had a cold, but it ended up being ground glass in my lungs. I was planning on stopping for a bit of a break so needless to say, I did. I am now on a, "chemo holiday". The main thing I did not like about Enhertu was that I had to have an infusion every three weeks and I live far from Mayo clinic so that has been a challenge. My insurance just decided to approve Everolimus, which comes in pill form. I will begin this treatment after my next scans in two weeks. Some people report terrible side effects from Everolimus while others say it isn't so bad. I am hoping Everolimus works for me if not I may go back on Enhertu but at a lower dose. Also, for certain days on Enhertu I felt nauseous but taking Ordansetron worked for me. Hope this helps.
