Keith, it's different for everyone and yet in many ways the same. You will both find your best support from people who've been through it, and this often starts with one's fellow chemo-appointment folks.
Don't forget to take some music on earbuds with you, and to be kind to yourself. And laughter-- it may come in odd places and will always do you a world of good.
Thanks for telling us about it. And telling and telling, in the days ahead.
It's a marathon, not a sprint... take time to look about, on this journey.
All the best,
