This was the case for me! It took me months to titrate down to 0 from Sertraline. Withdrawal side effects were terrible, and I’m pretty turned off to SSRIs in general now. My past doctors talked them up as “safe”, and treated the ramp down process as a tiny inconsequential mention.
I had tried to stop after stabilizing on a half dose, 1/4 dose, etc., and the side effects were too unpleasant so I had to start back up. I could only stop after I titrated down to 1/8th, every other day.
