constipation
"Have had constipation for years and years.  Over the counter medicines were not reliable or caused pain.  Did my own research and found MO.   What a thrill.  Inexpensive, reliable, no side effects.   
After using it for awhile I stopped and found I didnt need it. Now after a very holiday season of eating and drinking I find I'm constipated  so I'm back on magnesium for awhile to reset my system."
