Naloxegol
"I was an opiate addict for 24 years been clean for a year. I have always had trouble with constipation. I was taking OTC stool softeners when I'd go 4 or 5 days without going. I would be in so much pain I would literally put a glove  on with vaseline and DIG it out. Movantik has been a lifesaver I take 1 every night have coffee in morning and go. Little cramping first couple days but no withdrawals or nausea. I have lost 14 pounds in a month as well. Very happy."
