tednsal,
Welcome to HW. I am sorry your husband is having a rough time with this series of chemo treatments. For me, spicy/savory foods were much better than anything sweet when I was going through the bad taste part of each cycle. I was so hungry due to the Prednisoe and Dexamethasone that I kept my appetite even when things tasted worse or when I had low-grade nausea. I wrote a summary of my adjuvant Taxotere experience and includes some of the issues you mention: https://www.healingwell.com/community/default.aspx?f=35&m=2469594
Take care and best wishes for your husband.
