What a horrible situation to be in. I wonder if they are giving you dose-dense? Those are powerful chemos, I think 3rd generation. Maybe they could try a modified regime? So much depends on things like how old you are and all the other indicators they take into account. I see you are in Darwin - probably limited options for second opinions there but it might be worth a try. At the very least get onto your oncologist and the hospital and your cancer nurse and see if there aren't medications they can give you to make it more tolerable. And if you feel your body just can't take it, call an ambulance and get admitted to Emergency. Let us know how you go.
