My guess is that knowledge varies from MD to MD….a lot depending on age, training, specializations and clinical beliefs. Your psychiatrist sounds very conservative — and that isn't bad. It strikes me that the Ashton taper is well known – at least among people on this thread. It is certainly worth trying. If you can go more quickly great…if it takes longer…that's fine, too. Keep working with all your doctors – I find it's good to email or VM to keep everyone in the loop – and good luck!
