I always say that everyone should know if you are stuck with a physician from the bottom or top of their class 

Talked about an hour with dr. Saya today. He did not think the prolactin was high enough to cause trouble, but gave me the choice of taking cabergoline and see if symptoms improved. From my reading, it's too high. So I picked up the caber in town, 20 bucks a pill. Thankfully only need 4 a month. Boy, sure would be nice if one get get insurance in this country. Hopefully it brings me back around.
