My symptoms are fluctuating too..some days it's worse than others..you might've eaten something that actually helped your stomach to settle down..(I know..it doesn't sound likely these days to me either, but every now and then I try to eat something and strangely enough it makes me feel better, and helps on my symptoms for hours to come..) so who knows! If you get worried too much, you can test (=torture) yourself by smelling something that really makes you nauseated..(to me it means to turn on the oven a bit or put on a pot of water boiling, lol) maybe it "helps"..Good luck!
