Who said Winny and RU-486 was it? You can use Bromocriptin, Cabergoline and/or 200mg ED of B6. Personally, I take 200mg of B6 daily and then Caber as necessary. Never have problems controlling Progest. Also, it really helps to keep your estro in check too. Progesterone becomes more active and prolific in the presence of high amounts of estro.
