Don't overwork it, @Annetted That may not sound helpful, but there are so many variables you will send yourself bonkers trying to get ahead of the game. It's one of the few times that being reactive rather than proactive makes sense.
The main thing is to make sure you keep notes and let your oncologist, BC Nurse and GP know exactly what is going on. If you have pain, get painkillers. You may need laxatives or diastop. You may put on weight or lose it. Yeah, I know, not helpful.
You will have to find out exactly how you are going to react. There are commonsense things like checking your temp and drinking heaps and heaps of water, but you may have to make the rest up as you go. Marg xxx
