Worried about moment ec chemotherapy

I originally put this query in a different category but didn't get any replies and I think the Living With Cancer but is much more appropriate.

I will have had 12 rounds of chemo by Friday (paclitaxel, carboplatin and immunotherapy).  It was relatively straightforward and was v pleased that I did not have any sickness.  Quite tired 

Now am about to enter 2nd half of chemo  with e +c once every 3 weeks. 2 people have told me it's really "hard core" but I'm hoping there will be drugs to counter any nasty side effects.

What is other people's experience of it and any hot tips for managing it?
