Your sobriety date is the last day that you drank.
Your sobriety experience is everything you built up before and after drinking. Sobriety dates are celebrated, but it's the experience you pile up that is the most important by far. Take everything you'd built up and work it like it's your day job.
There's no putting aside a drink for our sobriety dates. We must stay accountable. Every sip of booze must be acknowledged and dealt with.
