Lifelong constipated woman here. There are 2 things you haven't tried. Well, 4 I guess. Number one and the thing I think is most effective is dried apricots and prunes. I thought the prunes would be gross but they are actually quite good.. 2) Enema. self-explanatory 3)suppository, also self-explanatory 4) Magnesium citrate. It's a bottle you get at the pharmacy and while it takes bad I've discovered the cherry flavor can be mixed with a lot of sugar or a single serving packet of Crystal light. You want the bottle to be really cold so stick it in the back of your freezer for 20 minutes or so before you drink it. Try 1/2 bottle first. I don't know how long it takes to work but when it works your bowels will be clean. They use this a colonoscopy prep (with another drug) if that give you an idea. That's why I really recommend the apricots of prunes first.
