I have a volume knob on that voice now, but it took time and the steps to install it.
In early recovery I went to meetings every day (sometimes two). I went to an outpatient IOP three days a week. I got in the habit of talking to others in recovery who had been there longer.
The voice got quieter for a while each time I did that. - Time and the work I have put in help me to quiet it on my own now. When I can't I reach out to a few close friends in recovery and they help me. Sometimes I just go to a meeting and it shuts off.
