You are right to not take anything you do not feel comfortable with. Did he start you on the full 60 mgs? (or try too!) Most protocols for Cymbalta start at a much lower dose, and then go up to the higher dosage. I have read on this site about a lot of people that have a really hard time trying to discontinue taking the Cymbalta. Just do a search on Cymbalta, lots of posts to read! Good for you for taking a stand against someone who sounds more like a bully than a Dr.!
I hope you feel better soon!
PS-I am not saying Cymbalta is bad, actually I am taking it right now!! I am not sensitive to drugs, and I think it is a good fit for my situation, I have only taken it for about 6 weeks, so I am not really in a position to say if it is successful yet, but even now, I am only on a 40 mg. dose.
