Perceptual distortions in late-teens predict psychotic symptoms in mid-life

That's why I listed a myriad of symptoms. If someone solely believes that, say, some people are following them, that's one thing. But if someone thinks people are following them and that some entity is implanting thoughts into their head via futuristic technology, then they're very likely in a state of psychosis.

If you haven't committed any crimes or done anything noteworthy, it's especially unlikely any government is going to devote resources to following you. If you know you've committed some serious crimes, then it's certainly a much more rational fear and could be real.

Also, if you're really being followed by a government IRL, odds are you're not going to notice it unless they want you to notice it, and that pretty much doesn't happen unless you're an important figure traveling to a foreign country and they want to intimidate you. It's not impossible that you could notice it, but when multiplied by all of the other probabilities, it's very unlikely. Especially if you hold other paranoid beliefs.

>Who decides what's real? Is it not real unless you've got audio?

If you hear someone talking to you but you don't see anyone nearby, or if you hear something/someone while no one else near you hears anything. But, yes, if you try to record it and don't hear anything on the recording, then that would also be an indication.

For the most part I haven't had many psychotic symptoms aside from during lockdowns when I've had constant, obsessive thoughts about suffering. Sometimes I'll lay awake unable to fall asleep thinking about people forced into slavery, human trafficking, torture, my own future death etc.

There are lots of different anti-histamines with different effects and side effects. Salt and adrenalin are apparently 'natural' anti-histamines, I would go with them over medication, though sometimes I need anti-histamines for allergies. That cyproheptadine seems to be contra the general trend of anti-histamine -> pro-serotonin (I think the mechanism here is that once the histamine is gone, more serotonin can be made, this takes a long time, days not hours or minutes).

a quote from the above link: "Nutritional treatment for drug and alcohol users will depend on the results of a test for blood histamine levels. In one series of such analysis, all users proved to have high histamine levels, leading the scientist to conclude that this abnormality – with its impact on brain function – is a major force in creating addiction. [Nutrition Guide for the Prevention and Cure of Common Ailments and Diseases, Carlton Fredericks, PhD. p.58]"

I'd swear I've seen Carl C Pfeiffer quotes saying similar things but haven't turned them up after a cursory google. I should mention I know during opiate withdrawal many addicts take antihistamine to counter the itching from the histamine released by the opiates, which might confound attempts to establish a link to addiction.

I have particular problems with allergies during the summer months, so it's not just eating too much salad - "salad bowl depression", ha - but a combination of both tree and grass pollen. Another thing I found interesting is that there are foods that are low in histamine but high in histidine, which gets turned into histamine in the gut.

Optimism, a healthy dose of skepticism and diary for food and activities seems to be a good way to check things out personally, although not exactly scientific. One thing I found interesting was the claim that too much histamine in the stomach prevents vitamin-c from being turned into gut serotonin. So oranges are high in vitamin-c but also high in histamine, so the 'material' recommends ascorbic acid instead. Personally I enjoy oranges more than any other fruit so I go ahead, I don't think I have the worst symptoms anyway.

One final edit, a lot of vitamin and multivitamin tablets quietly include 'folic acid' so watch out for that avoid them and buy tablets that do not have it, if you are convinced of an issue here (this is also in a lot of food as fortification as you already know).
