Hi,
You sound so confident about your decision. I think that's awesome. I hope previous pdoc (Can we call him p-pdoc?) takes you back. Yes, be a good patient now will you? I guess the lithium is helping because it sounds like you want to stay on it and that's a good thing.
Your promise to be good reminds me of a story. When my sister was in the hospital she had an argument with a couple of the nurses. She looked at her chart and saw a notation that "patient was rude." LOL We laughed about that for years afterward. I kept saying it probly said "patient was nude."
Anhow, I'm glad you feel sure of yourself and impressed that you called T and told him what you needed. Bravo! I know how hard it is.
Take gentle care.
