I had similar issues while estradiol was in the 20s. I got some research chemical pramipexole and dosed it up to 1.5mg qd. This cratered my prolactin on the next blood draw, but the sides were gone. I have since dialed the dosage back, and I am awaiting the next lab results now.
I do not think a doctor will prescribe pramipexole or cabergoline while you are in range, so the research chem route might be your best bet. You could tell your doctor you believe you have restless leg syndrome, your friend had great success with pramipexole for his RLS, and you want to try it.
