Nick, I wanted to mention the anti nausea drug Emend that I have been taking during my treatments. I have had 4 chemo, given once a week,amd 18 radiation treatments and I haven't been to sick until now. Trush in the mouth can be a problem and cause terrible pain but they have given me medication for that as well and the sores in my mouth cleared up. Everyone is different as you know and what works for one may not for another, but you may check with her Dr.'s and change her anti-nausea medicine. I wish you all the luck in getting your Mom to complete her treatments. I know how she feels as I to am so sick and it does get hard. Best to you all, Angel
