Hi Abkbjbjb
I am just out the other side of chemo for breast cancer. I still have a long way to way but so far so good.
I am not much good on your exact questions but I found these things helpful. Note am in no way a medical person so this is just personal tips.
Lots of homemade soups, batches when I had the energy and defrosted and eaten in small portions on the bad days.
My mate loaned me a juicer, so squished up whatever fruit and veg was in the house, nothing too citrusy, which was gentle on the stomach.
A nurse friend did recommend wheatgrass for cancer treatment, but tbh I had let it slide.
Just ate normal dinners, heavy emphasis on comforting starchy childhood type dinners, whatever you fancy really, it's more important you eat and enjoy something pleasant and fairly nourishing than pick sadly at a plate of steamed kale. Eat small portions and give it a half houR to settle. You can always go back for more if it agrees with you. Dont get freaked out though, you wont be this delicate all the time but some days you will be, most likely days 3 to 7.
After every meal take a spoon of bio yoghurt, I found it great for preventing mouth sores, and seemed to work it's way down the gullet helping prevent heartburn and settling the tum as well.
Some new and different flavoured teas, you might go off your normal favourites but the comfort of the warm mug is great this time of year and it's great for keeping hydrated.
Rest rest rest. I dont know your circumstances but rest whatever chance you get. Take any help. Dont be superwoman. Save your energy for your kids if you have them. Then dp/close family & friends as applicable. Adults will have to understand and the house won't fall down for lack of cleaning (obv hygiene is important but being Mrs Hinch is not!) . Your job if you work has rules they have to stick to so let them look after themselves too til you're back on your feet.
You will have to be infection aware, not just covid but any infection. My consultant said he had patients who tested positive for covid and they still came through ok. The real problem is if you catch it your treatment plan will be delayed til you're all clear and its best to just get on with it, if at all possible.
I feel for you. It's so daunting at the start. But the treatments these days really are so good, so try to keep hopeful. Bad days WILL pass and allow yourself whatever you need to get through them. I will keep you in my thoughts and prayers (hope you don't mind the prayers bit)
