20 months is wonderful! I like your question or your therapists' What does Sobriety look like - changing into pyjamas to seal the deal - yes!
For me sobriety is not having to have an endless conversation/debate/argument with myself, starting at around midday, about whether or not I was going to buy any alcohol - running through the dialogue with myself, often knowing what the outcome would be but kidding myself it would be different, or maybe tricking myself into some ludicrous deal with myself only to go back on that deal hours later, distracting myself but glancing at the clock, checking how much time I had before I wouldn't have enough time to drink it all, making up some random lie about food we needed so that at the last minute I could go and buy it. That total bull**** has gone - totally gone - I need never have to listen to that utter nonsense again. Thank you Obladi for reminding me of what sobriety has won me.
