Magnesium oxide
"I came upon this website as I was looking for different uses of magnesium oxide (MO); my initial reason for taking MO was for nerve pain, but I found it very interesting that people with my same "issues" used it for constipation, heartburn, even nausea, so I decided to "up" my one-a-day dose to at least twice per day, and wow, the difference is quite fantastic! I must say I'm a skeptic by nature but, MO is an inexpensive way to deal with common side effects from pain medicines, etc. Without any hesitation, I recommend this "medication" for anyone with stomach problems, especially females suffering, like myself, from endometriosis, interstitial cystitis, and/or Celiac, or any auto-immune disease."
