Hi Julia,
I finished my last cycle four weeks ago. I too had FEC and then taxotere. I bought revitanail (clear strengthening nail polish and used that) either black or brown nail polish - the point is to have a good sun barrier and to keep the nails strong while you are on taxotere. I was also offered very cold mittens to put my hands into whilst I was having my IV as it will help with not only nails but with loss of feeling at the tips of your fingers later. The nurses will explain it all to you.
I absolutely hated the taxotere was the worst experience of my life - thru the pain and lethargy. Bare in mind this is my experience and everyone is different. Ask many questions and if you are not sure ask again.
All the very best.
