Wendy, my husband is 12 weeks post treatment. I am guessing you do not have a PEG? We had a standing order for fluids and my husband had to use it multiple times. I cannot support what Christine says about fluids and nutrition enough. I will tell you that numerous rough days during treatment we had to return to a discussion about those two items. If you have 3 days of consistently meeting your intake goals, you will see some things improve I promise. Also, we have just discovered the joy of blending foods in the Vitamix. My husband survived treatment on VHC Boost we could only get from Amazon in our area. Just to give you some hope, today my husband ate three meals! So hang in there.
