Constipated for 1 week, been drinking milk of magnesium ;doesn't work, stomach hurts and hard to function, can i switch to miralax, (polyethylene glycol) hard stool?

Try suppository?: Have you try any suppository at all? You may want to revise your dietary habit, to eat more fibers (fruit &vegetables or may take fiber supplement) and drink plenty of fluid daily. The longer the stool sit on the colon, the more it will become harder..... Suppository may help you. If it's still not successful, may need to see doctor asap. Good luck!
