Hi- I don't know what your situation is now, but after dealing with mucositis (vomitting the stuff up on an hourly basis), and going from 119 to 105 very quickly, i was finally admitted to get a peg inserted. Have Had it since Fri pm, still hurts, but its a marked improvement.
The thing is tho, it was finally a GP Doc ( not RA or MA specialist) who finally got me on a combi of Mucinex and a Scopalmine (?-aka Transderm Scop) patch that is worn behid the ear for 3days at a stretch. Unbelievable how much it helped me. No more vomitting, and much less spiiting the goop out.
Just passing along my experience in case it can help others-
