Hi Diana,
No, my husband is not new at this. He was dx'd in 7/05 and went through two different types of traditional chemo plus radiation. His reaction to traditional chemo was dreadful. So now he is on tarceva and is stable. But the tarceva is not going to work forever, so they are talking about alimta next.
I am telling you this b/c it seems you are relatively new at this. So the fact that your dad has to go to the center almost daily for shots and such is good, because they are doing a thorough job giving him the necessary additional medications which make it easier on his system to deal with the chemo. Most people experience some side effects some more than others. He is almost bound to feel bad in the days after the chemo but mostly should feel better a few days later.
I know that life is difficult right now for you and your loved ones. I will keep you in my prayers. By the way the www.thewellnesscommunity.org has excellent on-line support groups for patients and also for caregivers. Maybe you want to look into this. I will keep you in my prayers.
