Overate....Recipies for a homemade purgative?

I totally overate at a bbq and have been lying on the couch in pain, wishing only to get it out of my system. I'm not bulimic or anything, I just want to get it out! Does anyone have a method other than sticking my fingers down my throat. Like I said, I'm not bulimic, and this doesn't appeal to me at all, but neither does being overstuffed.
