The oncologist don't really comment on "complementary" theraphy, however they don't deny it that it helps. However you need to tell your oncologist, so it is on the radar. So I got my acupunture through a bc friend, and tried it on my 2nd round of chemo - 1 session "before" and 1 session "after" each round, it helps my body recover faster. It also helps my digestive systems and calming my mind. The sessions were very calming, as you have to lay there for 15-20 minutes while the needles still in you. (it doen't hurt, so don't worry). Not sure where you are based, I am sydney - if you are this way, I can send you the contact.
When you are as sick as I was, you would try anything!! Have they perscript you the magic nausea tables call "Zofran" yet? Here is some drug review fyi:

p.s. It can be a costly exercise, the health fund pays a little for a fix amount, but you can claim portion of it through tax when you reach the threshold.
Biotene .. yike, I used the gel, it was awful. I think loads of chewy-gum and tic-tac are better choice!!
all the best! You will get through it.
