Second time chemotherapy

Continuing the discussion from April 2024 chemo starters:

Hi, I just found this forum and really could do with some tips on how to cope with side effects.
I had her2+ er- pr- 13 yrs ago . I had surgery and six rounds of fec with herceptin for 12 months. It was tough but I managed it well.
I have now been diagnosed with her2+ er+ pr-
And started my first of 6 rounds of docetaxel/ carboplatin + phesgo for 12 months , surgery on completion of chemo this time.
This is day 7 of my first chemo and I still feel so sick , exhausted. What day would I start to feel a little better? I can’t get out of bed for the exhaustion.! Any help or tips greatly appreciated
