Oh, yeah, Those are definietly two different things.

Sometimes or mostly they probably are withdrawal or low med-level related, but occassionally I get them even when I've taken my medication as prescribed. I also suspect they are linked to my social anxiety medication as I'm using, unorthodoxically, benzoes designed against epliectic seizures for it.

Edit: u/bostwickenator is also to my understanding 100% correct, so +1 to him.
