Gorbachev was already winning it in 1989. The issue with his anti-alcohol campaign was that it coincided with a lot of other stuff happening in the Soviet Union and USSR collapse torpedoed it before permanent results could be achieved. Deregulation of the economy and relaxation of limits on private business of course sabotaged Gorbachev's effort in that direction quite seriously, but campaign was still giving out noticeable effect in a just few years.
Gorbachev was not “winning” at all. His campaign was quite absurd because it included cutting down production of the quality wines and as far as vodka was involved, it’s shortage was countered with the skyrocketing moon shining. Technical spirit also was all over the place and so were less healthy sources (extracting spirit out of glue required just a drill). Actually, the process started much earlier, during the last years of Breznev’s rule, when shortages of vodka started even in Moscow.
The same campaign would not be successful at any time. One that the Bolsheviks picked up from, out of all people, Nicholas II also was not working due to the moon shining. If anything, the Bolshevik leadership never applied it to themselves and it kept tricking down the social ladder.The same kind of campaign but performed in 70s would be successful especially with somewhat better planning and less sweeping symbolic gestures like outright destruction of wineries.
