What are some natural remedies for Cymbalta withdrawals?

Hello, I am asking this in regards to my mother who has been on anti depressants for about 15 years now. She is desperate to wean off the Cymbalta but is going through the withdrawal "hell" that so many face. We are a very natural and herbal family and I was just wondering if anyone had found something natural to help ease the withdrawal symptoms. My mother is basically bed ridden right now with nausea and vomiting, she can’t even keep water down. She feels like shes going crazy again. If anyone has been through this and knows something that can help please help me out! Thanks so much.
