I agree. Even if there is no anxiety or pressure in my family, my stuttering can fluctuate every minute/hour, which means it can be primary symptoms. I can only experience temporary fluidity with any glucose intake, filter coffee or magnesium complex. I think my stuttering is caused by a Neurotransmitter imbalance and I use an external timing, metronome, etc. I use. I can speak fluently. :/ The only thing that draws my attention is that I still have high anxiety symptoms outside :) In short, I think I would be very comfortable if I used psychiatric medication.
