I've always worried that an ssri would decrease my mental performance. Maybe worth revisiting. Can the help you learn better / focus more by blunting depression / stress?
The practical upshot of which is that the various drugs affect various people quite differently. I have trialled various pharmaceuticals over the years for my assortment of mental health issues. Some I will never take again. Some I take only if I really need to. Some I take every day. Some work great for me but suck for people I know. Some suck for me but have changed others' lives.
The only way to know how a given medicine will affect you is to try it yourself under medical supervision.
