Hi @Lizzie75 Absolutely ditto to what @kmakm has just said re TC. Don't be too hard on yourself and do what you have too to get through it. Day 3 to 4 was crash day for me until until day 10 or 11, and if later you have to take it hour by hour then so be it. You'll get through it, it's just grotty.
Cross fingers that all goes well for you. It's true everyone reacts differently. I found it good to keep a day by day diary as to how I felt and what I ate which will be handy to remember for your next chemo. Also don't suffer in silence as your pre and post chemo meds can be changed if need be to make things easier for you. All the best and thoughts are with you. xo
