It sometimes works, it's contraindicated for certain people, comes near the end of the list of things to try (wait to see if you get better and get some excercise/sleep/sunlight being low risk interventions for mild depression) and even when it is used and does work, starting/continuing antidepressants and other treatments is recommended.
It's just one more tool in an incomplete and inconsistent toolbox, not 1 weird trick your pharma company hates.
I know of one person who recently had some success with it, but they tried other things first.
