You can add L-Glutamine to the mix as well as this is used by many cancer patients to prevent mouth sores. You can pick up L-Glutamine at places like GNC which sell an unflavored mix so you can add it to anything. Typical dosage is about 5g to 10g (*NOT* mg but g=grams) 3x day.
Here is one, of many, research papers on the effect of L-Gluatmine:
