Hi! So happy to hear about the consult. I hope it is everything you could wish for. I find it encouraging that this doc has posted so much info about different treatments and that those statements jive with what I, at least personally, have seen in the literature. It sounds like they are familiar with the options. What a concept!
Maybe write down what treaments you have tried and what has or has not worked for you. This includes meds and any negative reactions. Don't write a book, just a shorthand list.
Take notes while you are there if needed. Ask where the doc thinks you should start and lay out any ground rules you have. I told my PM right off the bat what I did not want so we were both clear and he was totally respectful of that.
Good luck! Let us know what happens!
