How long do laxatives last in your body?

I finally got relief from my constipation and the laxatives cleaned everything out, Or so I thought. Last night, I was waking up through the night having diarrhea and it wasn’t every so often, it was every minute of the night. It was a pain in the *** (no pun attended) because I really needed that sleep. So can someone please tell me how long laxatives last in your body for? If it helps, the softener i took was docusate sodium and the laxative i took was Lactulose-Pharma.

    Bulk-forming laxatives can have some effect within 12-24 hours but their full effect usually takes 2-3 days to develop.

    Osmotic laxatives such as lactulose can take 2-3 days to have any effect so they are not suitable for the rapid relief of constipation.

    Stimulant laxatives usually work within 6-12 hours.
