nausia

If someone has the same symptoms please reply. For the last 5 months I've been having nausia spells throughout the day. It starts as butterflies in my satomach, then i get lightheaded and have a dizzy feeling and sick to my stomach. i never throw up , but it lasts maybe a minute or two..All day and all night about 4-5 times an hour. It wakes me from my sleep, even though I take sleep medicines. I've been diagnosed with a hiatal hernia several years ago and an ulcer, which I take nexium. I'm waiting for results from an endoscopy, but i don't feel like it will show anything else but those two. I've waited 4 months to get in to the specialist, and after telling him of the problem, he tried to dismiss me. So to get me out of his office , he ordered the endoscopy. The family doctors idea was to start me on domperidone to make the food i eat travel quicker through my system, which hasn't done a thing for me. i've tracked when i get the synptoms and it doesn't seem to matter if I have or haven't eaten, whether i'm sitting, standing, driving or sleeping . I'm starting to think its psycological, noone seems to know what it is. Please help.
