I'm perscribed XR 10 mg and I want to start gradually lowering my dose. I still have 70 days till my next appointment and want to be off it by then so I can't ask for an IR script. I've read (on this site and elsewhere) and my Dr. has instructed me to not divide the XR capsules. What is the reasoning behind this? Is it just because it is difficult to divide or are there medical reasons?
