I was legitimately in my late 30s when I first realised this about myself too; the sheer amount of caffeine I can be on (upwards of 300mg pre-workout for an evening gym session), and be pretty much asleep before my head hits the pillow.

I have no idea the long-term impact this level of stimulants would have on my health (but I doubt it’s good), but it works!

My wife is extremely jealous of this, if she so much as looks at a bottle of Coke after 4pm she has trouble sleeping… 🤣
