constipation
"This product does what it says with terrible pain! First off... i would never recommend this product to someone who experiences IBS like myself. Seems that the posts praising ducolax are from people who have only had LIGHT constipation discomfort. 
I now understand the "near death experience" that Ducolax is. If you ever ever experienced true food poisoning that leaves you expelling from both ends simultaneously this is exactly like that! Cold sweats, nausea, diarrhoea and vomiting accompanied by the worst cramps of life. I mean I can actually say I thought I'd need an ER visit & if you've tried this and lived to tell the tale YOU KNOW! 
I would absolutely recommend taking this on the first day of your weekend with zero plans!"
