I cut down to one or two drinks a month, became more aware of my own emotions and developed some responses to them that help even things out.
Having a normal routine helps. Like a “normal person” routine where you go to sleep at a reasonable hour, get up at one as well, eat healthily, exercise, wash yourself, spend time outside etc. making it a routine means it’s something you do automatically.
That was really hard for me for decades. Sometimes I’ll still be awake far too late or skip a shower and have to catch myself.
