Thanks to everyone who replied. I was wrong, I thought I read about the medication here, but it was actually in a discussion forums. http://forum.canadianparents.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=272465&fpart=1 The medication is miralax or peglax I guess for us (Canadian resident) we can order it through http://www.pegflakes.com/index.html My son went through too many episodes, and tried many remedies that was suggested in here.
