constipation
"So, I'm 5'3 and 135 lbs. I have tried Dulcolax in the past for constipation, but decided that it might be a better experience this time. I took 2 pills around 5pm I think. It says to take 1-2 for adults. I had horrible cramps and abdominal discomfort. About 11:50pm I had the feeling that I needed to have a bowel movement. I had a lot of diarrhea, but it really does help with constipation. My advice, take 1 pill. If you can't go after that, take 2 the next day. Honestly, once it kicks in, you will feel so much better after it's all over. If you can't handle cramping very well, you might not be able to handle the effects of this medicine."
