Hi Ping,
It does build up so each round will probably be slower to recover from than the last. It's just a matter of waiting until it passes.
I didn't have FEC, I had 4 x AC followed by 4 x Taxol. After the 4th AC was by far the worst but I was then glad to find that the Taxol didn't keep building on top but started fresh.
Rest as much as you need but it is helpful go for a walk if you're up to it. Or at least go outside.
I remember going for a walk with my Mum & for a change I was the one needing to sit and rest.
Best wishes
Allicat
