Molly, Even though your sister has completed the actual radiation treatments, radiation is still doing it's work and will for a few more weeks. Along with the other tips, someone on the board suggested burning a peppermint candle for nausea--I don't know if it works, but if your sis is feeling that bad, it sure can't hurt to try it. I know it might be hard for you to believe right now, but your sister will continue to get better. Keep us posted on her progress. Sincerely, Donna
