I truly understand your frustration and being "so tired of all of this since nothing works." Yesterday I had a horrible day. I am supposed to take Bisacodyl every third day if I have not had a BM. And since I've had C-diff (which I'm over but my intestinal tract has not returned to "my normal"), I'm having to rely on this regimen. Yesterday I was so uncomfortable, heartburn, feeling awful and absolutely thinking I don't want to live like this. Today was so much better and I'm going to try to use the full dose of Miralax recommended for adults and hopefully steer away gradually from the Bisacodyl. I know you said the Miralax didn't work for you yet but I hope it will. I was afraid of using even one adult dose because it had caused "leakage" in me before and that's not very desirable when you don't have any control. But it doesn't sound like you have that problem, thank goodness. I would encourage you to at least try what your Dr. recommended. I also read on here that there are Magnesium citrate gummies, OTC (over the counter) that have helped someone. And Prunlax mini tabs (also OTC) were also helpful to this person. They were also taking Miralax at night. I wrote it all down,....it's worth a try to find a regimen that works. I've been this way all my adult life because I learned I have a tortuous intestine, way more intestine than I need for a person my size. It has caused me grief for a long time. But I had developed a livable regimen before I developed C-diff from an antibiotic the dentist gave me. (Clyndamycin). I was able to have BM's on my own but not since C-diff. (I also take 8gm of psyllium sprinkled on my oatmeal or cereal daily,and metamucil crackers. I get tired of it too but let's keep the faith and never give up. I know that awful feeling when you're having bad days,................I hope it helps to know you're not alone and hopefully we'll all find something that finally works for us individually.
