Can someone explain why diarrhea from taking Magnesium Oxide has slowed down. I started 2 days ago and it had me racing to the toilet after an hour of intake. Now....nothing. Some grumbling in my colon and I'm sure it will soften my stool, but nothing explosive like the first two days. I hope this is normal since I've read it's more common for Magnesium oxide to cause diarrhea =S
