When do you experience brain zaps?

I’m curious what others’ experiences with brain zaps are. If you experience them, is it generally when you have used too much and over-ramped, or during comedown or withdrawal?

I can’t quite figure it out for myself because I use multiple ROAs during the same day at times, so my high can be all over the place sometimes. I get fierce brain zaps when my body is anxious. They are mainly triggered by unexpected sounds or visual stimulation, like when something bright or flashy pops up on screen while scrolling. It all comes on when feeling overstimulated; however, none of the information I can find says it's due to neurotransmitters being depleted or from them being too high.

What has been your experience?
