SSRIs for me sent me all over the place, I was cycling up very quickly just to be dropped back down further than before and was down longer and longer. That is what eventually led me to changing pdocs because my current one didn't question any of that (also I had a lot of weight gain from the SSRI and I wanted to change that). The new pdoc had me coming off the SSRI and starting an anti-psychotic the first day with her.
