Before my diagnosis, I had a lot of stomach issues. I would throw-up that yellowish stuff, sometimes other things to (I know TMI ), but I had that problem all day - not just in the mornings. Since I have gotten on all my "AS meds", my stomach has calmed down. I do still have to watch what I eat and stay on the meds, but mostly my stomach is better. Do you sleep through the night? I am just wondering if maybe the inflammation is worse at night? I know my stomach seems to be related to inflammation, which I can tell now, but has taken me 3 years to be able to relate it to anything. I know it really SUCKS!!! It is one of the many frustrating aspects of this disease, because I do believe it is related - maybe it just seems that way to me.
