Ahhh my friend. My heart aches for you.
I've been through a similar but different medication situation. My liver and kidney functions were normal but I was brain dead. I really couldn't even read. I knew all the words, but I couldn't figure out how they went together. Anyway, I stopped. I eased out of some meds and just shit canned others. 15 years later it is so worth it. My poor doctor occasionally tries to give me something but if she can't give me hard and fast answers (including how long) I just won't play.
I'm here too. Anytime. I don't know if you still have my phone # but I have yours.
