I hate sugar (cancer survivor), BUT…when your glucose gets low it can trigger anxiety. As a former drinker I can attest this works; carry some hard candy with you & when you feel the anxiety coming-on enjoy some sugar. Your body (especially first few months of abstinence) craves the sugars the alcohol once converted to & provided. Also try William Hoff breathing therapy. It’s really great & stops my anxieties in seconds but the sugar is KEY. Edit; ANY sugar will work.
