SIDE EFFECTS: Enlargement of the breasts (gynecomastia) is a not infrequent side effect. Rare side effects include diarrhea, cramps, drowsiness, rash, impotence, irregular menstrual periods, and irregular hair growth.

Maybe the first piill DID have some bizarro ingredient? Maybe something you were allergic to?
Why not try to find out from the manufacturers what the inert ingredients were?
