Hello.  I just finished thirty-five sessions of radiation and three sessions of chemotherapy for cancer on the base of the tongue and in the lymph nodes of my neck.  I'm worried, because I cannot find anything at all that does not burn when I eat or drink it.  I used to be able to drink instant breakfast, but it burns.  I can eat cream of wheat, but that is certainly not enough.  Could you please give me some suggestions for foods to try and approaches to eating?  I do not have a feeding tube.  I had a severe allergic reaction to the fentanyl patch and to morphine.  I am able to take hydrochodone once or twice a day, but it just takes the edge off the pain.  Nothing actually stops it.  I have huge ulcers under and along side my tongue on both sides and white blisters  (not thrush) on top of my tongue.  The last time I wrote, I had not yet begun treatment.  Because of encouragement from this site, I had the full treatment.  However now I am once again in need to hear some experienced voices.  What steps can I take to eat again? 
Thank you!  
Johanna
