I think AVRT is useful for anyone who questions their alcohol ( or any intoxicant) consumption.
In AVRT , the Beast( desire for the intoxicant) doesn't cease to exist and is forever capable of barking AV, recognizing , identifying and dismissing the bark is always 'useful' , and when familiar with the technique is practically effortless. " Nope" takes about a second to think.
"Long sober" implies an alternative and is therefore AV. Not being familiar with the specific AVRT nomenclature doesn't imply that one will not continue to be an abstainer , but becoming familiar with the technique and its concepts could allow one to be more comfortable or confident and cement the veracity of their resolve.
It seems an alternative would be to in a frame of mind that sees oneself as sober and 'hoping' to stay that 'way' , but hesitant to say or use the n-word , which by the lens of AVRT is unrecognized AV . " Never say Never, count your time and bide it, because you don't / can't know what can derail your 'sobriety' come what may"
