Here is my take on it. Every 'requirement' that we accept as a necessary condition for sobriety can actually be a future excuse to drink. (e.g. I drank because I didn't go to enough meetings; I drank because I got too tired; I drank because I didn't work my CBT worksheets; I drank because I didn't reach out, etc.) The AV loves to create these for future use (i.e. anything will can create doubt about the ability to stay sober is AV). If on the other hand the only requirement to not drink is to...well, never drink, then you have made life much more simple. There are no more convenient excuses that you AV can use to convince you to drink.
So why am I here? I am inspired by stories of success. I can help others. I can do my part in keeping the RR story straight (as I understand it). None of these are 'requirements' for my sobriety, however.
