Bisacodyl
constipation
"I took one tablet a week ago, with very little effect. The morning after taking it I did go to the toilet but it was very small.

Last night I took two tablets at around 10pm, and woke up naturally at 7am and needed to go. I did have pretty explosive diarrhea which lasted for about 5 minutes, but absolutely no pain at all, or sickness/fainting//dizziness etc. Every time I have gone to the toilet to pee since then I have also had a small amount of diarrhea but still feel absolutely fine in myself. Feeling very cleared out and my stomach is so flat for once!

I am horrified by all of these other reviews and do feel like I've been lucky, but then again, people are much much more likely to write about bad experiences than good ones."
