Depakote is a medication used to treat seizures. I have not heard of it being used for opiate w/d either, but that doesn't mean it's never been done. Good for you in deciding to take your life back! And welcome to the site. You will find lots of valuable information here.
I am not familiar with Depakote, other than it is used as an anti-seizure med. Clonopin does help with the w/d process. Look at the Thomas Recipe in the Health Pages on the right side of page.
