I personally do not believe AI's will help with prolactin. Used stuff that causes high prolactin in the past with a high dose of nolva to help out, didn't do a thing. Also I have not had a problem with this in the past when I have used nolva during times with only high estrogen.
As far as cabergoline goes, which is what I think you are suggesting luv, I would read around on the forums and read some of the articles about heart valve defects from it. There is debate whether the dosage is what caused it to happen or if it is something that happens either way. The point was with the dose used 1/4 of users had heart valve defects that can only be fixed by surgery.
