MiraLax
"I have gastroperesis and rarely have a bowel movement on my own. I've gone 3 weeks easily without a bowel movement. It's to the point that when I do go on my own, we know that I am severely constipated and that it HAS to come out. (Abdominal xrays continuously show I'm backed up, even after going). Miralax is not a "miracle medicine" for me. It works, but only after a few days time. However, considering that typical laxatives only cause me gas and bloating, but no relief, I can't really complain. Magnesium citrate, Linzess, Reglan, Amitiza have all failed me. This is the only relief that I can ever get."
