Since Janine is far too modest to plug her own books (lol,) if you have not yet found out, you find can them on Amazon.com (just search her name)
Actually, she has 2 books out, but Unraveling deals more with advice on how to handle, and very useful, in-depth information on a variety of symptoms including DP/DR...
I think that they will be very helpful...
Best,
Jon
