Just a note of encouragment to hang in there. We did 3 hd ivigs starting a year and a half ago. We went from an angry, anorexic, OCD, vocal tourettes, hallucinating insomniac to a sweet little boy after 2 1/2 years of ######. He is on prophylactic antibiotics and fish oil but doing great...not perfect..but great. He is 20# heavier, sleeps like a baby and is in a typical small school (where he is comfortable telling his friends about PANDAS) I never thought we would find him again. Hang in there, they can get better.
