If you had stones stuck in your intestines for awhile chances are you'd know it because they would fester, and that hurts. chances are all you did was take too much oil for the power of your digestion, which means it would be a good idea to keep a close eye on your tongue, and if it's pale and white, use warming therapy - hot spices, ginger tea, garlic, onions, very few raw veggies.
Just to be on the safe side it would be a good idea to eat a high-fiber diet for awhile and supplement with extra fiber.
to get over the oils overdose, lecithin may help, digestive enzymse certainly will, and the cleansing drink. Good luck! :)
