You can self-experiment too, actually

You are having trouble with something in your life like falling asleep, or focusing, or whatever, and you decide to take some supplement or drug. The problem that you will often face, unless it’s something with really strong effects, is that you don’t quite know if it’s working. It might feel like it does, but how can you know that it’s not a placebo?

Oh, you don’t care because it seems to be working anyway? Sure, but placebo effects will fluctuate based on your mood: how confident are you today that the supplement/drug is working? And how confident will you be tomorrow? Placebo effects are unreliable and we can and should do better. In this post I’ll show you how to estimate the actual effects to be able to rely on those instead. I will illustrate step by step with my own example, since I’m currently running one.¹
