Magnesium citrate
"I had surgery 5 days ago, had not pooped since the day before my surgery, so a friend of mine went to CVS and bought me the grape flavored, as a get well soon gift. She knew more than I did apparently. ..it took about 3hrs and then it started working. .needless to say I have been going a lot, so to kill time I have been reading the reviews on this medicine and I can relate to some of them...some are hilarious,  but I needed something to do while I waited for the lives to renew on my game...after all I'm just sitting here."
