"I have only been takeing this for a week now but WOW.  It works so good.  It took 4 days to start it&#039;s action.  It was like I was normal again.  I am 31 and have had constipation my whole life.  Higher fiber has got me through until a partial blockage and intestinal damage 2 months ago.  Now with Amitiza I feel less bloated and a movement everyday on one pill in the morning. I feel so good! A little chest tightness but it gives me no nausea yet.  This is a great medicine."
