I agree – go in w/a list of questions?
You mite not get answers, but the doc will know you are no ‘pushover’ and just go w/HIS flow? You have legitimate questions, and deserve legit answers! This is a time when the phrase: ‘I’ll get back to you later’ will NOT do! And make it clear that you want to KNOW what is happening NOW that’s new, different or more complicating to your already complicated life!
You are really gonna have to assert yourself about now? And seek answers. I truly hope that you do GET answers!
