Eric,
My husband had chemo along with his 37 radiation treatments. He was meant to have chemo every week, but only ended up having 4 treatments due to low white blood cell counts. For him, nausea would set in about 3 days after chemo and last for a couple of days. Chemo made the treatments more difficult, but I know that now, at 15 months post-treatment, he is glad that he did everything that he could to beat the cancer.
I know that this is a really difficult time for you. But know that things will get better!
