Thank you Lynn. I always enjoy reading your posts. You are so caring and on top of things. I have responded to a few of your posts (like the one on carriers with symptoms) and I think we have lots in common (like feeling the need to leave good careers to care for our sons). You are such a strong person and I am so glad that you were persistent and got the medical care your son deserved. I am happy things are going better for him now. Thanks again for your response. Good to know titrating isn't that unusual.
