Naloxegol
"Frankly, I’m surprised by the bad reviews. My constipation is severe. It at one point sent me to the emergency room. Reason? A stimulant laxative. Never again. I have never been a “1/2 pill is too much girl”. Movantik doesn’t overwhelm my body. 
My husband lost his mother to a burst bowel so he is especially concerned. Never was a “poop a day girl” either. Having found Movantik is why I’m breathing a sigh of relief. If I can ever get off the opioids, it will be a happy day. But until then, I thank the Movantic developers. True I, on occasion, will take a nausea pill but I did that before Movantik. Now you can’t pry it from my cold dead hands!!! It helps me and our piece of mind to have Movantik assist me."
