Bisacodyl
constipation
"My husband got this for me since I haven't been pooping that well lately. He told me it was better than any others, because you don't get stomach cramps. WRONG. I took 2 a couple of hours ago, and now, my stomach is in the worst pain ever. Thankfully, I have had a BM, but I don't think I will ever take Dulcolax again because of the severe pain."
