s unlikely you can handle the problem by simply adding a magnesium supplement, since your
blood pressure has always been low. Adding magnesium could tend to make the
blood pressure drop even more. Hopefully there will be other ways, besides taking Nexium, that your acid reflux symptoms can be addressed. FWIW, I was on Prilosec for years, finally had to stop because of the side effects, and now am off of it with no problems.
