i take phillips MOM tablets. I take 2 each night on a regular basis, and up to 4 if I am getting backed up. I also take a stool softener like colace that has a senna laxative in it. Very gentle way to keep the workers moving. its easy for me to get stopped up, as I have a gastro issue where my tummy doesnt want to move, so I like magnesium as my drug of choice.
