How can I avoid constipation from this rice?

I just ate like six cups of white rice with strawberries at about 12 midnight tonight. Both foods cause constipation.

How long will it take before I start to pass this rice? When should I take an over-the-counter laxative so I can time it so my stools dont come out painfully? Now? Tomorrow?

that depends, dont take laxative unless u really need to, it will pass. i say about a day or two but it will be over in no time. best wishes.
