Since AVRT has crept into this thread, I think it's important to point out the difference between "sobriety" and "abstinence" in AVRT jargon.
"Sobriety" is the tentative condition of not having alcohol in the blood due to a vast array of conditions that a person is meeting in their daily lives. Sobriety is born of the belief that by myself, I cannot stay stopped. I must reach out to other struggling addicts with the primary purpose of the rest of my existence being to learn about my powerlessness and meet those numerous conditions that will keep me "sober" one day at a time.
"Abstinence" is the condition of not having alcohol in the blood along with a plan to not swallow any more alcohol for some predetermined time into the future, AND of not needing anything other than personal brain activity to secure that condition. For addicted people, that predetermined time is always easiest if set at forever with the Big Plan, due to the nature of the Beast and its AV.
