I am going to post for you the link to Professor C Heather Ashton DM site. Dr. Ashton's research has centred, and continues, on the effects of psychotropic drugs (nicotine, cannabis, benzodiazepines, antidepressants and others) on the brain and behaviour in man. Her main clinical work was in running a benzodiazepine withdrawal clinic for 12 years from 1982-1994.
I think you will find her site very helpful.
Take care and I wish you the best of luck in your weaning process.
