Kadcyla - does it get easier?

On dose 5 (next week) and want to ask if the side effects get easier to deal with (nausea being the constant horrible pain in the a***)?! I had my dose reduced after dose 2 and it’s definitely “easier” ie not 24/7 but it’s still hard and the majority of my days between doses I have mild to extreme nausea. I take the meds, I try ginger tea, shots, fresh ginger - you name it! It affects my appetite and mood, I am eating so little these days, it’s awful.
I am on Kadcyla forever - I have stage 4 BC with secondaries in liver, bone and brain so there is no chance of me coming off this unless the disease progresses again and they change my drugs/chemo.
Any advice gratefully received! Thank you!
