I didn't have TNBC but I did work through chemo -3 months of A/C and 3 months of Taxol ( herceptin for 12 months). I didn't have nausea or fatigue (did have a few other side effects). I took a day off for A/C once every three weeks and half a day for Taxol weekly. But it seems almost impossible to know how you will go until you start. My reactions to chemo treatments remained much the same throughout but I did develop some unexpected side effects that required medication but did not affect me day to
day. Some side effects of Taxol can be irritating - I lost my tastebuds and had a rather bloody nose periodically.
I agree with mum2jj - working was a wonderful way of keeping cancer in some sort of perspective. But as reactions vary wildly, it's not possible for everyone and some people prefer to spend time on other things. Your work project sounds really important to you and doing it will be a very positive thing which is good. Attitude helps but it's not always enough.
With a little one who needs your time too, take any help you can!
Best wishes.
