Hi, I was on Enhertu for 13 infusions. My tumors were stable and even shrunk some. I found it much better than Doxie and Carbo. The first days were fine because of the steroids. Day 4-6 or 7 nausea and fatigue but I was out walking and driving, By around day 11-12 I was playing pickleball My doctor had wanted to give me a rest after 6 months but I requested to go on another 3 months. I then had a bit of a lung condition known as ground glass...look it up, not really glass;-) I am on a chemo holiday right now and going to try Everolimus in two weeks hoping for as good a result as Enhertu. If it doesn't I may go back on Enhertu but a lower dose. The very best to you. Hugs!
