Colleen, I am curious to know if you have found out what is causing your problem as it sounds very similar to what I have been suffering with for months now.I get the 'bubbly'feeling and nausea,but don't vomit.On my good days,I feel great, but then out of the blue I'll have that sick, bubbly feeling for days.Like you I sometimes eat only crackers for days to keep it calm.Anything you have found out would be helpful to me.Thanks and I hope you are feeling better!
