You must realize that the process is going to be "hard and long." If you went from 150 to 37.5mg in five months, then you did it too quickly and learned what does not work. I was able to quit entirely--twice--by decreasing too much too soon, but extreme withdrawal symptoms hit two months later! That defeats my purpose, as I had no choice but to return to the drug. Now I'm tapering by no more than 10% over time. The Maudsley Deprescribing Guidelines explains why this is necessary. I created a spreadsheet for myself, and it will take me three years to taper properly. That's my best chance for success and I am taking it, because I want to be free of this horrible drug.
