My husband is 53 and has had small cell lung cancer for 16 months and is now stage 4. The cancer metastasized to his brain, but was treated with radiation and the brain is clear now. Currently undergoing treatment with Alimta, after trying all other types of chemo. Does anyone have any experience with Alimta as a lung cancer treatment? He is on his 4th round. He is extremely tired all of the time, and coughs alot. I was wondering if this is normal - he takes the treatment every 3rd week, and I was expecting him to start feeling better towards the end of the 3rd week. Instead, he seems to feel just as bad as when he first gets the treatment.
