Hi,
I’m on Lyrica and Pristiq. They help, but no cure. In a rather interesting side note, one of our cats developed something called “Twitchy Cat Syndrome.”
it is an imbalance in the nervous system, similar to Dysautonomia. Cats was caused by a shock to the system from steroids.
Our vet prescribed anxiety medication for the immediate issues, but also gave Stanley (cat), antidepressants to try and reset the nervous system.
It worked, we slowly increased dose, then after a few months, we slowly weened him off.
He is almost normal, still has spells of the Twitchy Cat, but very infrequent.
So, it appears to work in cats! Good luck!
