@Blossom1961 heartburn was an issue for me on and off during chemo. I would 1) stopped drinking English breakfast tea completely at the start of chemo (stopped coffee afew years ago due to anxiety); 2) have a tiny bit (half-teaspoon) of apple cider vinegar in warm water before I ate anything once a day in the morning, 3) no regular alcohol since diagnosis 22/6 last year, a glass of chambers/ small amount of wine with a special dinner out; 4) half-way through chemo my cousin, who is a midwife, said slippery elm worked for nausea and heartburn. I started to take one before breakfast and one before dinner, and I continued that till the end of 9 weeks taxol. It really helped keep those problems at bay for me; 5) as others have said exercise - I walked outside every day, 6) I’ve been taking ultra muscleze twice daily for muscle pain. I’ve found it has the added benefit of keeping depression at bay!!
hope this helps. 7) chocolate - my daily choc diet is no more since diagnosis: I eat chocolate on and off, but never in bulk, like I used to. 8) I eat more fresh fruit and more greens than before.
