GERD
"I have been using Miralax and psyllium every night for about a year and wanted to try Linzess, but my doctor was hesitant to let me try it.  Possible side effects.  Anyway, after some research, I realized the Nexium I have been using causes a Magnesium deficiency.  So now I take a multi-mineral capsule and a 500mg Magnesium capsule 3 times a day with meals.  I have been able to cut back on my prescribed medications and have some hope that I will be able to get off them completely by adjusting my mineral intake.  Try this, because your bowels cannot function without enough minerals."
