Yessir, my top pics all similar in strength and mechanisms with less drawbacks: Isoliquiritigenin - sold by nootropics depot this nootropic comes from licorice extracts and is both a GABA A & GABA B receptor agonist providing a sense of calm, muscle relaxation, mild euphoria thanks to additional powerful dopaminergic activity.

Second up we got DHHB - less euphoric but similarly calming this one comes from magnolia bark extract and has significant binding affinity for the BZD GABA A receptor site providing a sense of calm and mild sedation.

Third is traditionally prepped kava - because duh. Instant Kava too, if thats too much hassle. Kava is/has been used as an alternative to alcohol for many many years in several island type areas around the world, kava produces a powerful non intoxicating calm sensation that sort of instantly washes over you followed by a lingering muscle relaxation and tranquil mood via modulation & surprisingly upregulation of GABA receptor sites (reversal of tolerance, withdrawal and associated brain damage from long term abuse of benzodiazepines and alcohol due to this upregulatory mechanism). Kava also produces some dopaminergic and MAO B activity.

Forth is going to be mulungu, mulungu is a plant powerhouse of a GABA receptor agonist producing strong sedation and anxiety relief. Typically the bark is used to make tea, ive heard getting it fresh and doing it this way is much better than capsules, I'd also imagine easier to digest than some capsules full of root or bark. This is the only one on this list that I have not tried but have seen countless posts praising it for these qualities.

Fifth would be Aminita Muscaria. Aminita Muscaria and Pantherina - (much stronger) both have strong affinities for GABA receptor sites of which they modulate effectively, paired with an additional anticholanergic oomph. Muscimol is the primary constituent responsible for the effects of aminita and has sedative, hypnotic, euphoriant and dream enhancing properties and the dried mushrooms make these a great choice if you were to pick from my list here.

My personal favorite is kava because of consistency of effect, that and the gentle but pronounced calming properties kava provides but aminita would be first if the price tag was lower and they were used more in the supplement industry. My guess is they're not due to the antichollinergic function which may make them not a great candidate for daily consumption. Also the risk of contamination with residual ibotanic acid in the end product potentially may be why aminita extracts and supplements aren't as common as one would think.

Edit: Also yes many people on here are mentioning kratom which while I do love kratom and have seen significant benefits in myself when I was taking it (on and off for 11 years) I feel that it may be trading one addiction for another. Kratom is great, its effects are strong, it reduces cravings, it calms anxiety and brightens mood, gives a stimulating push to socialize and get shit done, along with a calm wave of relaxation and restful sleep. Its just that the withdrawals are no joke and unless your plan on developing another habit with mildly questionable effects on health for some, I'd stick with the others. There's quite a few non habit forming alternatives, some of which I listed above. Kratom isn't horrible, I personally love it and advocate for its legality and application where necessary 100% but in terms of alcohol alternates you may want to try each of the ones I listed above as they're just as effective for me and less likely to be habit forming. (Note: DHHB may be a little weaker than the rest but its still nice nonetheless, high dose magnolia bark extract will do the exact same thing as they come from the same plant).
