I was looking at your dates of chemo and post and comparing them to my rounds of FEC. I remember for me days 3 to 7 after the FEC were the worst in terms of nausea, sweats, headaches, body aches etc. My oncol prescribed some anti-nausea tabs for me and upped the anti nausea pre-meds for chemo. Speak to your oncol, tell him/her everything you are feeling during and post chemo and they should alter the pre-chemo medication for you and prescribe some post chemo meds such as anti-nausea and steroids. These helped me through the FEC. Good luck.
