When I let my guard down and am relaxed around family, my stutter improves because I’m not self monitoring my speech so much, therefore there’s no real anticipatory anxiety around my close family. When I’m meeting up with friends or work colleagues for a social gathering, my anticipatory anxiety sky rockets and surges the adrenaline and dopamine in my brain, so I tend to experience more tension and stutter more. Anti-anxiety meds is helping me with this a lot now! After 2-3 alcoholic drinks, the GABAergic effect kicks in and puts the brakes on the dopamine surge, and I become more relaxed and therefore more fluent, temporarily.
