Also worth noting, that with teas, if you're not accustomed to drinking them straight — maybe they're too plain or uninteresting at the outset — you can also opt for blends that usually will mix herbs/flowers/dehydrated fruit and the like to give different flavor profiles. Your local store will have the basics, but online stores (like
Harney & Sons) will run the full spectrum and also help provide insight into the different varieties.
Also, not sure how much of a coffee head you are, but be mindful about temperature and steep times with teas. Lighter teas prefer lower temps (lest you scorch the more delicate flavors) and steep times times, like with coffee, can change the flavor by over or under extraction. The tea will usually tell you on the box what they aim for, but you can adjust accordingly. Also, tea can typically be steeped/re-used a few times if you want successive pours.
For herbal teas, I'd be remiss not to mention a nice Moroccan styled mint tea w/honey as a crowd pleaser, as are any jasmine teas that may be tossed with citrus blooms. Easy sipping for any time of day.
I would steer clear of Japanese style teas (eg, sencha), unless you like Japanese styled flavor profiles (think nori, as the teas tend to be very vegetal and dry) and similarly with matcha (strong grassy flavors). Those are more of acquired tastes.
Like the OP, I love my coffee and can drink it at night with zero qualms, but I also wanted to branch out and teas are just…fun. So are cocktails. And amaros.
But for my good habit side, teas, kombucha, and mocktails should do the trick, as long as you're mindful about the sugar intake (been tinkering with non-alcoholic liquor style subs, which can be interesting).
