Ask HN: Are there any safe alternatives to coffee for all-day sipping?

The realization that my current coffee consumption style may have adverse effects on my health has prompted me to seek safer alternatives. Throughout the day, I take veeery slow sips of black coffee without any milk (guess I like its bitterness), as I genuinely enjoy its raw taste, however I've found alternatives such as tea to taste too watery.

I'm on the lookout for alternatives that offer a similar taste profile, with little to no negative health effects for sipping all day.

If you have any recommendations I would greatly appreciate it!
