Blind tests specifically? Take, e.g., soda and diet soda, decant into identical containers with hidden labels, drink one, and log any effects before you check what it was. The brain is powerful. Some people experience real headaches because they think that WiFi or other RF gives them headaches. But they won't get a headache from radio waves they don't know about.

I don't intend this in a mean way. If you do find out that it's something else you could get relief from said migraines. Like the MSG folks who are probably just not drinking enough water when they go out to dinner, or are nervous about Asians or something. I once took placebo and a low dose of MDMA in a blind study and got them backwards. I was embarrassed for some reason but our brains really do construct much of what we perceive as raw sensory input.

I just know if I have more than 1 serving it gives me migraines

Might want to blind test this if you haven't already. See: MSG panic

I didn't want to lump women and enbies together so we need to wait for a third person to make a post

I think hexbear sent me here: https://elan.school/. Graphic novel about a troubled teen abuse camp stemming ultimately from Synanon. Content warning: this sent me into a funk for like a day.
