Here's the best site on the 'net for information, guidance and personal contacts for benzo addiction (Valium, Klonopin, Librium, Xanax
, Ativan, Serax, etc.):
go to this site and access the papers written by Dr. Heather Ashton, a leading authority on benzo withdrawal.
Based on Dr. Ashton's papers, I think your doc should switch you to Valium first, then slowly taper the Valium.
