Docetaxel comes with a different set of issues, but I didn't get the debilitating headaches, so hopefully you won't either.
Watch your temperature for the first week after each dose. Mine crept up starting day 4.
Docetaxel caused more bone and joint pain for me, including the Neulasta, it was quite sore especially around the chest and jaw. loratadine (Clarytyne) really helps there.
Diarrhoea was pretty savage the entire time for me, and only let up about 2 weeks after the final dose.
Good luck with the final stage, you are half way through!
