I took my 72 year old sister to a new doctor, a geriatric internist, who diagnosed her with 2 types of depression. He put her on 30 mg of Cymbalta. She has been on it for about three and a half weeks. She is arugmentative, short-tempered, just a real pain. I have been holding my temper with her, but I am dealing with my health issues too. She can't remember anything and when you are telling her something, she first says "I don't remember your telling me that and as you proceed she starts yelling "Yeah, okay, I remember, stop talking."
