As you probably already know, treatment for cancer can lead you, almost gently, through one thing you had never imagined before after another. Take things day by day, don’t fret (or try hard not to) about things that actually haven’t happened yet. Chemo is a big bogey and it can be very challenging but not always. I had no nausea or fatigue, worked happily through treatment. The hair thing is a nuisance but I found a synthetic wig easy, convincing and very useful (never imagined doing that either!).
As everyone else says, stay away from Dr Google. It will almost always lead you down (rarely lift you up!) a wrong road. Best wishes.
