Lol I will provide a small anecdote as a warning from my own life. I was at a point (pre-diagnosis) where I felt my caffeine intake had reached an addiction-like level and had decided to wean myself down to a more sustainable level. I’d read about adenosine receptors and the different substances that can act as stimulants/inhibit adenosine. I was starting to get a bit of a caffeine headache + drowsiness and the good idea fairy told me “hey why don’t you have some chocolate instead? Theobromine is an adenosine-receptor antagonist so it might help without consuming any caffeine”

This led to what was probably the worst headache of my life. I don’t know enough pharmacology to understand how exactly that worked, but it was terrible. Having a cup of coffee reversed the effect pretty quickly, luckily.
