Dulcolax
"I have had constipation ALL my life and I'm 50. I've tried everything. And I mean everything. I've had slow transit test which proved I have a sluggish gut.  The Doc recommended ducolax so I only take one and by the morning I'm going. I'm now taking then every third night. As that's the only thing what shifts it. I have no cramps no pains nothing. I've been reading all these comments. Some I've never had those experiences but I have never taken 3 or been recommended 3... So my advice would be one if you don't go take one next night. Also Doc recommended probiotics from health store AMAZING. Hope this helps guys.."
