I'm wondering about something a bit beyond the simple "what's the maximum dose not to exceed?". We all know that caffeine, consumed wisely, has a very favorable benefit/risk ratio: improved focus, energy boost, better athletic performance, and even some suggested long- term health benefits from studies.

So my question is: for a healthy adult male, what would be the ideal quantity of caffeine in milligrams (mg) per day to maximize benefits (focus, energy, well-being) while minimizing downsides (anxiety, poor sleep, jitters)?

I'm not looking for the dose to pull an all-nighter or break a record, but really the "cruising" dose for optimal daily health and productivity.

I'm a newbie and I don't know if it's very effective...

I'd like a small software on Linux, with a modern GUI that allows me to save certain important blog articles.

Wallabag is not interesting for me because it's too heavy (Docker)

I DON'T WANT ANYTHING SELF-HOSTED

The emergence of social media has destroyed all the small communities to standardize communication and information.

It's a bit of a digital version of rural exodus. And since 2017/2018, I've noticed that everything that, in my opinion, represented the internet has disappeared.

I've known Lemmy for a few hours and I feel like I'm back in the early spirit of the internet.
