Coffee and tea have been banned for practicing Mormons for a long time. Caffeinated soda was kind of an "extra credit" ban for decades until the church more recently started pulling back on that.

It's not even that. It's just blocking the receptors that tell your brain that it's tired.
You are still exactly as tired as you were, you just don't feel it.
It's marginally less dumb than nicotine when ingested routinely.
For anything where you'd be concerned if an idiot was trying to do it, caffeine is not a great idea.
> Caffeine is a stimulant, which means it increases activity in your brain and nervous system. It also increases the circulation of chemicals such as cortisol and adrenaline in the body.

I'm pretty caffeine sensitive and I get a crazy buzz from just one cup of coffee. It's not just not feeling tired, I literally get high.
I was happily addicted to it for years and other than a couple withdrawal headaches when my routine got disrupted* the only ill effects was occasional morning crankiness.
I expect I'll become addicted again at some point in the future. Probably in the winter with a nice hot mug on a snowy morning. I'm looking forward to it.
I can't imagine any state or religion banning caffeine. It's the safest, most wonderful drug there is.
*Any restaurant or convenience store could fix my headache for me.
