I don't know if this would be of any help:

They had a suggestion from a a board-certified family physician who specializes in pain and addiction who said,
“The best way to stop this drug is to put the patient on fluoxetine (Prozac) for one to two weeks. You then stop the Prozac. Prozac is so long lasting that it gradually decreases blood levels slowly enough so that the discontinuation syndrome doesn’t happen.
“This is simple and inexpensive. It is important, as you say in your article, that people do not stop this medication [duloxetine] on their own. However, it is not necessary to go through the ‘Chinese water torture’ by such a prolonged and unnecessary tapering regimen.
“Since most physicians do not know this simple trick, it is up to the patient to ask their physician to use the simple method.”
Those drugs are really rough to get off of. I've heard of some people experiencing "brain zaps" when trying to go off of that one.
The site advises that people make sure to work with a physician (hopefully a knowledgeable one) as they get off of these drugs. Plus, I would do a lot of research before starting.
