Any tips on docetaxel.

I have nsc lung cancer and targeted therapy is no longer effective. My lung cancer dr is recommending docetaxel infusions. Anyone have any advice.
I’ve been in two clinical studies, have taken standard treatments and an immunotherapy so that’s why I am wary.
I was doing so well on the targeted therapy for almost two years. It made me so sad to face another treatment but trying to be optimistic. Thanks for any advice.
