When do you get the last consult with the neuro? Will you have a "diagnosis" before you leave Mayo? Have they firmed up the sero-negative Sjoren's diagnosis?
I know you are bone weary. It was such a struggle when I was there. I cried some of the nights because I was in such pain and so tired. But you worked so hard to get this appt., did so much preparation for the trip, spent so much money, etc. etc. Stay until it's finished. It's important. If you have need of it, the Mayo optometric (think that's the word) I'm brain dead. anyway, they make a wonderful moisture chamber eyeglass. I wish I'd stayed to get one.
Good luck, grit your teeth and finish this.
