I stutter, I know what you mean. Sometimes there will be a stretch of a month maybe when I just feel like I have less control. I usually associate that with drinking too much caffeine, not sleeping enough, going through something else in life life (not really present in the moment), feeling or sense that someone or group doesn’t like me or doesn’t have patience/in a hurry, etc. it usually just goes back to a normal level on its own. It is a cycle. There is a psychiatrist in Southern California at UC Riverside, also I think director of NSA- Dr Maguire. He pioneered using very low dose psych meds and has had good results (he stutters too). Worth looking into if you haven’t given it a try. https://www.patientfusion.com/doctor/gerald-maguire-md-59700
