Not anecdotal, please see links to research in other comments.

Furthermore, just because something doesn't work for you, doesn't mean it doesn't work for others. Additionally, unless you've been keeping a log before and after you started the interventions, you should be at least skeptical about the difference you expect. It's entirely possible you got better, adjusted to the norm, and just think you feel as good as you normally do - while your "normal" is better than before.

Finally, the effect is more likely to be pronounced in people feeling worse than average. If your life is fantastic, you might not get much of a benefit from an intervention that has otherwise strong effects on people.

Makes sense. Thanks for sharing!

Fair enough

Sorry to hear that. Thanks for sharing!
