"when first taking this medication, i threw up the first few days of taking it. through the months i have experienced excruciating pain 2-6 hours after taking it. i normally take it around 11 or 12, right before bed. so between 1 and 6 in the morning, i am waken up by the pain. it&#039;s an aching pain with nausea. it is about once or twice a month, but when it occurs, it is unbearable! it lasts for about an hour or until i can fall asleep in the fetal position (the only thing that lessens the pain.) i am not allergic to anything nor sensitive to foods, so i am sure it is not related to consumed foods. it does have some positives. i  always receive my period on the same day and am not pregnant. so it does what it was intended for!"
