Search for "SSRI brain zaps" and you'll find a ton of info

I don't know how to describe it, but I always called them brain shocks. I don't know if it's what you're experiencing, but in my experience, they're caused by SSRI/NI/etc. withdrawal. I actually had a really bad experience with Cymbalta in which I was getting them even before it was time for the next dose, and then all the time, among other issues. Everyone's body reacts to things differently, but for me Cymbalta was a nightmare.
Definitely what other commenters are saying. I felt the exact same withdrawal symptoms and yes you'll find they're most commonly described as "brain zaps".
When weaning off it really helps doing it in a controlled manner by gradually reducing the dose (ofc do it with professional guidance). Even so, I felt them at each step down but the body/brain got used to it after 3-4 days. It can get scary or annoying but it eventually dies off.
I’ve been on the same med, same dose and 100% know the weird feeling you get from a missed dose. But completely forgetting what you did minutes ago? That’s not a normal effect with an SNRI. It’s also pretty unlikely that you’d develop a side effect after being on the medication. If anything, it usually goes the other way, where side effects fade away after being on a med for a while.
It’s possible that you’re getting some physical effect that’s unrelated to your Cymbalta, but maybe the physical effect reminds you of the feeling you get when you miss a pill.
