constipation
"Before my period every month, I get awful constipation for about a week before. I usually just wait is out because it eventually just goes away. But this time, I tried something new. I took 2 Ducolax last night around 9 and woke up at 9:30 with severe nausea and cramping. Let's just say, after hours upon hours today of the worst stomach cramps possible, crying, sweating, and throwing up, I'm exhausted. It kept it's word, it relieved all my constipation and I feel great now, I just wish all the side effects that came with taking it weren't so bad."
