I don't think the effect lasts long enough, and if you were to drink it often enough to maintain the effects, I'd be concerned about the addiction potential. Of course the addiction potential is also a thing with benzos, and benzo addiction is no fun. So I really wouldn't recommend either of those to treat anxiety tbh, but I can't make recommendations anyway because I'm not a doctor. But like, if it was me, I wouldn't use either of those. I'd take Benadryl (makes you sleep, makes you a bit more relaxed), Ibuprofen (helps with emotional pain too, not just physical pain), and I'd learn drug-free anxiety management skills (acceptance and commitment therapy is really good. There are apps). And if you can get antidepressants or another type of anxiety med, maybe try that.
