I also have TNBC, I have one more chemo left next week.
I did the weekly carbo and pax for four cycles, now doing the EC for four cycle four next week.
I found the carbo and pax on the first of each cycle absolutely horrible. It made be physically sick for three or four days, but the other two treatments of that cycle were fine for me weirdly, I could almost carry on as normal.
EC hasn't been as bad for me, in terms of sickness anyway - I haven't felt sick on it - but the tiredness has been pretty bad - I basically sleep on and off for the first week then start to feel ok. Annoying part of EC for me is it's made me lose most of my eyebrows and lashes, I kept them all the way up until EC.
I am only 36, so maybe age is a factor in how I have coped with chemo? Who knows! It hasn't been easy, but it's been doable. I agree with you re taste, I can taste the saline and there is one steroid or maybe antihistamine that they give via syringe driver that makes your bum feel itchy weirdly - hate that one. Also hate the white blood cell injections that you have to do at home, I hate needles so I really struggle with them.
With my chemo, I ended up transferring to a smaller hospital that does chemo - it's SO MUCH nicer than the big hospital, treated better, the nurses aren't rushing around, infusions get changed when the machine beeps (not like the big hospital whereby you can sit there waiting for half hour as they are so busy)
However the big hospital and smaller hospital are literally equal distance away for me so it made sense in terms of travel as well.
Can you change where you have chemo? Some places have those chemo vans that visit different locations for people that can't get to the hospital easily?
You can do this though, just keep moving forward and the end of treatment will get closer and closer
