Hi Brandi,
I'm 6 months out of treatment for tonsillar cancer (stage 4a), I had 3 doses of cisplatin and 7 weeks of IMRT. I'm suffering from the loss of taste and lack of saliva, too. It's better than in used to be,
Steamed veggies and fish ( get those microwave steamer bags at the grocery store) work well for me, Microwaved (like a baked potato) sweet potatos are good too, I also do well with shrimp, crab and tukey sausage. I dont do well with chicken (tastes like wet cardboard) or beef ( can barely taste at all, leaner is worse). Pastas with sauce are good to me, spaghetti or lasagna with plenty of sauce, although it was a while before I could taste tomato based things again, try an alfredo sauce if he cant taste tomatos. Chinese food is something else to try, it's usually moist with lots of sauce, and I could taste it pretty much all through treatment ( when I wasnt using my PEG tube). Try a Chinese buffet to see what he can taste,
Also, look for Biotene products (toothpaste, mouthwash, etc) for his drymouth, and just keep a lot of bottled water nearby. I got to where I couldnt stand the taste of our tap water, so my wife got mje some orange and mango Gatorade that wasnt too bad.
I'm glad to hear your husband is responding to his treatments. I've had a PET, 2 CTs and a biopsy since December, all clean and looking forward to another clean CT in June. I hope things go as well for you two.
Best wishes
Mike
