I took all the nausea medication that was prescribed while having FEC but have not needed anything on docetaxel. I found that eating frequently helped with nausea as did eating cold things. Peppermint can help too. Just eat what you feel like and what tastes ok for you. My husband was sent shopping daily for my latest cravings and some of them were not what I expected to feel like. Each round of chemo has produced different cravings!
I relaxed after the first cycle and learnt that you just go with whatever happens and remember that you do return to normal after a few days.
I think most people find it is not as bad as you imagine but I will be very glad to get to the end of it in a few weeks time! I think it gives you more peace of mind to know that you've done it as extra insurance that all the cancer is definitely gone.
Let us know how you go. Ask about any specific side effects as you go because you will lots of practical advice on here.
Take care and all the best.
