Constipation
"I&#039;ve had dulcolax many times before and always get a varied reaction. Usually it kicks in after about two hours. I will have moderate to severe cramps for a further few hours then diarrhea until the cramps stop. Sometimes I can&#039;t go for hours and am left with unproductive cramps all night. Sometimes there are no cramps and no effect (in this case I follow up with senna plus dulcolax the next day). My worst experience was a few years ago where I didnt experience cramps until the morning. After an incredibly painful few hours I passed an incredible amount of diarrhea over the next 24 hours to the point I was certain I had cholera; every 5 minutes I would need to run to the bathroom and pass a few litres of water."
