i should add, to explain, past the joke.
by "the cocaine effect" i dont simply mean that sugar is a stimulant, but rather, that sugar, like cocaine, hijacks the dopamine circuits and promotes dependence in a way that leads to abuse.
it's a known thing that cokeheads eventually no longer use the drug to get high. rather, they take it so that they can just function, because ceasing to take it would mean crashing into a most abject and dark depression.
some people have for now been working with the idea that sugar does the same thing, but sugar is so embedded in the culture that we don't notice. nevertheless this isn't new: there's a short story by baudelaire where a boy starts "experimenting" with sugar and gets hooked, hahaha. i need to find that, have not read it in ages.
but yeah, sugar, previously a pharmaceutical, gets added to a large number of foods, like your sushi pineapple something, so the theory goes, in order to make it addictive, and sell more. not just sweets but sauces, cereals, mayo, everything. which causes depression when one ceases to consume it. (this added sugar is why for me a lot of industrial foods taste utterly cloying).
i'd throw a wild speculation out there and wonder if your cyclothemia might not be related to sugar consumption patterns.
anyway if by any chance this subject interests you there is a fun and entertaining movie that presents/illustrates some of these concepts. you don't have to believe everything he says, but once you see some of it you start to wonder wft.
see:
https://www.imdb.com/title/tt3892434/
it's free on various channels right now, and it's well-made and highly watchable.
anyway for me it wasn't so much the biochemistry of the thing that made my eyes pop, but rather his highlight of the role of sugar in the culture that gave me almost a sense of red pill vertigo. "we equate sugar with love." goddamn. yeah... every stupid celebration includes a ton of sugar. also, the "bliss point." goddamn...
lemme know if you watch it, i'd be curious to hear your reaction to it.
