@julie67, I'm sorry to hear about your troubles. We've all been there. Chemotherapy of any type definitely takes a lot out of you, and it's important to rest while your body is recovering. Most people take months or years to recover. Show yourself some grace, as they say here in the South.

None of us are oncologists on this site, at least not that I know of. The best we can offer are our experiences and the experiences of others. It doesn't mean you will have the same experiences. As our doctors always tell us, "Every body is different."

The important thing is to know what type of lung cancer you have. The specific type determines the treatment. I had Carboplatin and Alimta simultaneously with radiation after my robotic surgery, and the primary side effect was tiredness. I received Vitamin B-12 shots before and after and took Folic Acid during chemo. That was over six years ago. I have the EGFR Exon 19 mutation, so I'm not a candidate for Keytruda and can't talk about what it's like to be on that.
