One or the other, Bro.
Both could cause a problem with a sort of dopaminergic syndrome, similar to meth. dementia.
I like Prami and use it daily, but it takes getting used to, couple weeks of being tired and loopy. Or take it before bed and I sleep better, but some people sleep worse...tricky drug.
Caber may be better for something used only during a cycle, as opposed to every day, because it's better tolerated. Though it's said Prami suppresses prolactin better, caber usually works more than well enough.
