Bisacodyl
constipation
"I took dulolax at midnight & got rudely awoken at 6am with the worst cramps & urge to go to the toilet, it was a horrific experience I've never felt so ill going to the toilet, it was like chocolate milk yuck!! I think my body was in pure shock as it took me 2 days to recover, I lost my appetite & slept a whole after my bowels had been emptied."
