Yeah, I've done it (though in my case not in a straightforward way, but have plenty of knowledge of G withdrawal etc to know it's effectiveness) To cut a long story short, after taking g 24/7 for 12 years I was in a relationship with an alcoholic, I should have guessed I'd get hooked too (have history kind of), packed up G for vodka, not massive amounts but 100 litres in 5 months, partner passed away (alcoholic death unfortunately, extreme addict herself), was emotional, drinking more etc, felt ill even getting out of bed, knew G only hope, just switched from Vodka to G (that was 24/7 though)....then my life improved so didn't need it quite so much and finally was too risky to order (and expensive from UK)(I liked my drugs to cost about 10 pence a go, a la G

) wouldn't dream of risking ordering through customs to uk now, and UK to UK darkweb prices are ridiculous.....When you stop the G helps to have some diazepam or baclofen (can be got on prescription, uk anyway)(baclofen not the valium)...personally people say that coming off g is really, really bad....I've not found that, found it pretty easy
If you check out research on using GBH/GBL/Xyrem/Alcover to resolve alcohol use disorder, it becomes obvious that it's the most effective treatment around. Of course the states and lots of governments are anti-G. Don't quite understand it. Alcover (G in effect) is used in Italy and Austria for precisely that use, recovering from Alcoholism.
Been off G for a year now, bit sad really, no semi-legal supply anymore. Might seem like I got carried away, 24/7 for 12 years, but to be honest G's got so many benefits, and everybody I know whose dabbled feel the same (though they tend to be introverted asperger's types, kind of anti-depressant for that type of dysfunction)
Only drawback is takes away motivation. Now I've had to stop I've also needed to study for lots of work exams, couldn't do it on G, fine without.
So the answer to your question is yes, lol.
