topsy Yes, definitely to the nail varnish. It stops your nails becoming discoloured. I favoured a very stylish shade of purple. Mine aren't too bad, although all fingernails are growing with a ridge in them, and I have lost the top layer of both my thumb nails.
I had very little nausea at all - I was on Emend days 1-3, and didn't need anything after that. I found I was a bit "looser" in the bowel department, more inthe second half of each cycle, so watch out for that. 
Usual tiredness crap and joint / bone pain, especially if you are on GCSF, which are the daily injections I had from day 3 to day 11. Do them yourself- it's dead easy. I found the aches and pains got much much worse when I had neutropenia infection, so worth bearing in mind if the pain seems unbearable. When I was not "infected" they were not too much of an issue and not in too much pain.
The skin on my hands and feet suffered in my 2nd docetaxol cycle, but not the others. They peeled and peeled and peeled some more, like how you used to put glue on your skin when you were a kid and let it dry and then peel it off. . . just me then. . . Anyway, get some nice handcream and apply lots. It wasn't painful at all, just looked like I had leprosy!
That is all I can think of right now - will come back with some more pearls of wisdom when I've eaten something!
