You only need caber if your prolactin is high (hello blodwork!!!)
0.25mg of caber twice a week is sufficient to almost put your prolactin to zero, but you need to take it for some time, prolactin has long half life, not like an AI that the effect is (almost) immediate.
I dont take caber unless I know my prolactin is high, dopamine is not something to be messing around.
