Laurie -
Not to be rude, but screw your doctor! He clearly doesn't know what he is talking about or doesn't care. Don't let anyone make you feel as though you are crazy or "sad", you are not. You are part of the "a lot more than 1%" of us who have been made a prisoner to duloxetine by doctors who really have no idea what they are giving people.
You are taking a generic equivalent with a different time release formula than Cymbalta or even other generic equivalents. So when you decide to start tapering again, I would suggest you to go slow because just one of the pellets in the generic you are taking is nearly 10% of your current daily dosage. You may even want to go back to the 60 mg dose and start again from there going more slowly, like a pellet every week or even every 2 weeks - just take your time and remember that it isn't a foot race, although believe me, I understand the desperation to get off this stuff!
I was forced by doctor negligence to go cold turkey from about 45 mgs (I had been tapering from 90 mgs (taken for 6-7 years) over about 3 months) about 6 weeks ago, and I am still struggling with withdrawal symptoms - but I have to tell you that I do feel a little better each day now (with the exception of the digestive upset - this is a tough cookie I have to say!) and I feel a mental clarity I haven't felt in years. So keep hanging in there, it will get better.
