Why are people so obsessed with Yerba mate?

Not hating bc I am here, obsessed with it too. But I want to hear why. For me it gives me a nice energized but calm feeling. When I wake up depressed, it almost magically snaps me out of it. I don’t know if it’s placebo or what. I’m on antidepressants and they don’t even have such an effect. It makes me feel like I can get through the day just fine, happily even. It makes me feel healthy too, probably all the minerals. I think it helped me drop 4 pounds that were impossible to lose. What about you guys?
