Will I have any withdrawal problems when it comes time to get off this treatment like I did with the Cymbalta and will with my fentanyl patch and Percocet? The Cymbalta was a nightmare on its own. So before I take this for a few years I want to know what to expect when the time comes to get off of it. No one told me what a hell I would go through with the Cymbalta. So I am trying to find out more info on this new one.
