@Newby24 I'm just joining this thread as I've been occupied for a couple of weeks with family stuff. I hope today is as trauma-free as possible for you. The other champions on here have given you all the best advice.
A chemo nurse advised me to take the anti-nausea meds regularly and pre-emptively: don't wait until nausea knocks at your door.
Ginger beer and ginger lollies are good if you feel queasy. I had no vomiting at all.
Your first cycle should give you an idea of the pattern of how each cycle will go.
Take your temperature twice a day. The hospital will tell you that if it's 38C, go to Emergency.
I had my hair buzz-cut. The remaining 1 cm started falling out after about 10 days; it wasn't uncomfortable - in fact I used to make a joke of rubbing it and spreading "silver fairy sprinkles". I chose turbans rather than a wig and loved them.
If friends ask what they can do to help, tell them "A prepared meal that can be frozen".
I hope you get a decent sleep tonight.
All the best .
