Hi Kryss! I am new to the boards as well. I too have had problems with chronic nausea, especially in the past 6 months (I was diagnosed with MS in 2008). After lots of GI testing, it's supposedly related to acid reflux disease. I have taken many, many acid reflux medications to no avail. So, on March 30th I am going to have lap nissen surgery done to strengthen my lower esophageal muscle. I was also wondering if this muscle weakness could be attributed to MS.
