There are days where I can have a cup of tea or a can of redbull or even an espresso and just go to sleep in 15-20 minutes. But there are also days where it actually works. What causes this erratic behaviour of caffeine on the mind?
PS: I don’t intake a large amount of caffeine regularly but it’s behaviour is kinda weird

If I can piggy back off this without needing a whole new ELI5, why is it that I can feel SO tired, but I lay down to sleep and can’t, but just resting my eyes for a while seems to have really helped?
