My Son Is Attempting To Recover From Benzodiazepine Use. He

My son is attempting to recover from benzodiazepine use. He is currently down to 1-2 mgs of valiium per day, but has almost unbearable periods of brain fog, confusion, anxiety, panic attacks, and suicidal thoughts. He withdrew from klonopin a year ago, and has been attempting to get completely off of the valium, but the symptoms have been too unbearable to completely stop. We need help. He sees a dr. regularly (the one who originally had him on klonopin for years), but the dr. is at a loss as to how to help.
