Hello, [...]. Although we would be delighted to learn otherwise, we are not aware of research studies on very long tapers (or specific ‘methods’ of tapering). Instead, each of us has to discover what works for us through a process of trial-and-error using the guidelines of (1) keep withdrawal symptoms tolerable and (2) maintain whatever level of functionality is required to perform essential daily tasks. Moreover, what works for us at one point of our taper may not work at another so we have to be prepared to make adjustments as we proceed (e.g. changes in method, reduction amount, reduction interval, dosage form).
