Caffeine is lowkey the most normalised and profitable drug addiction in the world, and it doesn’t really even do anything. The whole ‘giving you energy’ thing is a myth, all it does it make you tired without it. That’s why caffeine legally has to be listed as a ‘flavouring’ on the packaging, despite nobody on earth having a clue what it’s supposed to taste like
well caffeine mostly makes me pee. it’s a diuretic which means it makes you pee. that’s the thing it’s most effective for for me. other side effects include having an easier time shitting because it increases bowel movements. apart from that it is a mild stimulant that maybe makes me a bit more creative. i’ve observed it a couple of times but it’s inconsistent.
