This dynamic reminds me of an experience I had a year ago, when I went down a Reddit rabbit hole related to vitamins and supplements. Every individual in a supplement discussion has a completely different supplement cocktail that they swear by. No consensus ever seems to be reached about what treatment works for what problem, or how any given individual can know what's right for them. You're just supposed to keep trying different stuff until something supposedly works. One must exquisitely adjust not only the supplements themselves, but the dosage and frequency, and a bit of B might be needed to cancel out a side effect of A, except when you feel this way you should do this other thing, etc etc etc.

I eventually wrote the whole thing off as mostly one giant choose-your-own-adventure placebo effect. There is no end to the epicycles you can add to "perfect" your personal system.
