What's it like getting chemo and radiation for stage 3 lung cancer?

I have stage III non-small cell lung cancer and surgery isn't an option for me. My oncology team is discussing different treatment approaches using radiation therapy, either alone or combined with chemotherapy. They explained that chemotherapy can be given at the same time as radiation (concurrent), before radiation (sequential), or radiation might be used by itself. The choice depends on my specific tumor and overall health. I'd love to hear from others who've been in a similar situation and can share what their experience was like. • If you had concurrent chemo and radiation, what was the treatment schedule like day to day? • What do you wish you had known before starting your treatment plan?
