I would like to think that doctors become doctors because they have a passion for it. Unfortunately, that usually isn't the case. My ex boyfriend is working on becoming a doctor only because it is a high paid profession. My mother's friend's husband is a doctor for the same reason. He likes his huge house and boat. My current boyfriend's father is a doctor because HIS father was a doc, and he didn't know what else to do. So... I feel that if I have to cause a ruckus for a doc to listen to me, chances are I am at the wrong place. I've done enough swimming upstream in my life-- when I finally seek medical attention, it isn't so I can do more of the same. I'm so glad my physician now takes the time with me to see how I'm really feeling, instead of just staring at his paperwork and dismissing me.
Lithium is nasty stuff. You should read Betsy Lerner's book (if you haven't already), 'Food and Loathing'. She suffers from bipolar disorder and has struggled with weight issues all her life.
