How long after Castor oil will I go to the toilet normally?

The other day i took a swig of castor oil as i wanted to know i wasnt as constipated as i thought i might be, took stated dose on bottle with glass of water , before i ate breakfast this was around 7 -30 am, at 10 -30 i was empty, wore a diaper just in case, but opted to use toilet, good job i did, diaper would never have held the amount that poured out of me ! and i almost blocked the toilet bowl. Think this was saturday, its now thursday, no sign of any shit, how long do you reckon before i have to shit normally ?

A full dose of Castor Oil pretty much empties your entire GI tact, both small and large bowel. That's why it used to be used as the first step of a colonoscopy or barium enema prep. It was largely discontinued because patients detested taking it.

It takes a few days for your GI tract to get full enough for you to poo again. Eating a high fiber diet will hasten this filling.

Castor Oil does have the reputation for causing rebound constipation… after a poo forced by the oil, you tend to get constipated… but I suspect this is just due to the fact that by the time you colon refills with poo, it has dried out somewhat and can be difficult to pass out.

Never tried it, never will.
