wow reading all of this really aligns with some of my own discoveries…I have had issues with food additives for some time now. I can have a sip of something with artificial sweetener in it (unknowing) and I can tell you instantly as my stomach feels like I just ate a large rock. MSG can have me running to the bathroom in under 10 min. I have a friend who has been struggling for yrs with sililar symptoms as me and I finally said to her a few weeks ago that I am convinced she has EDS too! I have been put on an acid reducer because I was having chronic hiccups. I also take zertec regularly because I just seemed to feel better who knew!!! I feel more POTSY when I skip it. I just thought I was having a bad day! I do have to say I am also very affected by pressure systems that come through particularly drastic changes. I have recently gone on ritalin to help with my fatigue….It has boosted my energy some but mostly helped with my myofacial pain. when that happened it really made me start to look at all my symptoms a little differently.
