I have never met a Doctor (pdoc or otherwise) that know the slightest thing about psyche drug withdrawal. They all want to do it WAY too fast and they also think there are no such things as withdrawal symptoms.

But as Blue mentioned it depends on the drug and also the person. But no matter what do it slowly. I just quit taking Cymbalta and the doc wanted me to do it in 3 weeks, I said "no way" and I did it myself taking 3.5 months and I still experienced some withdrawal effects.

Benzobuddies is a good place to look for how to withdraw from various meds, not just benzos. You can also get a free copy of the withdrawal handbook "Harm Reduction Guide" (just Google it it).

Second thing you want to do (switch meds) sounds like you have the right idea but I have no idea about dosages to do it properly, again benzobuddies should have something.
