Having such a bad reaction to it lead me down a wild goose chase toward finding out the way my body processes serotonin ala a gene test, helped me figure out what was causing the depression to begin with.
Another reply here talks about how it seems to be a crapshoot for finding effective drugs and a lot of trial and error. I think that there may be promise in doing drug targeting genetic tests and possibly microbiome sampling as a way to help people avoid the run-around. In my case, knowing this ahead of time would have helped me avoid a lot of suffering and 3 years of obsessively searching for answers.
