For energy, you just to eat enough food, make sure it's good quality and balanced, drink enough water, and have enough electrolytes from food, salt, (and supplementation if needed). Sleep hygiene as well. Stimulant teas are add-ons, meaning they supplement a nourishing lifestyle. They do not replace it.
Alcohol is a depressant, not a stimulant. If you need to relax and let go of inhibitions, there's breathing exercises you can use. You don't need to resort external substances. Sure, you can have some chamomile tea or similar if you want to. It's not going to affect you badly. Just saying you have all the tools within yourself.
