I did find some information for anyone who is suffering from esophageal spasms. As some of you know, this has escalated for me over the past few months and it has been my primary out of control symptom. I read online and on this site that magnesium suppliments may help muscle and nerve function as well as muscle spasms. As the esophagus is a muscle and the PPI drugs deplete magnesium (as well as other minerals) I figured I would give it a try. I tried this Saturday and so far I do feel a difference. If I have them they are much less intense and less frequent. I am not sure if this is a coincidence or not but I plan to continue to take the suppliment. For anyone who is suffering from these spasm, try the magnesium suppliment.
