I worked up to 120 mg/day and didn't have too many problems. I got the stomach cramps, I think, but only during the night. Since I was sleeping, it didn't bother me except when I got up to pump. I was on that dose for 2-3 months. I am weaning down now and am currently at 80 mg. I don't get the cramps as much. A lot of women stay on it during their entire nursing/pumping relationship. I think it is pretty common among women who EP as it is harder to maintain supply.
