I think I might have had this test done on me years ago. I was having dizzy spells when I'd turn corners or stand up too fast. I went to an ENT and they did the test with air in my ears. I was so sick the lady had to grab the garbage can for me and I was crying uncontrollably. She said nobody has ever reacted like that before. But they did not have me not eat or drink that day, that I can remember
She did tell me that this is the worst part of the test for most people and when most of them get sick... Some just mildly sick, some of them... pretty bad!

I had that test many many years ago and I hate to tell you...it is NOT fun. Of course when I had it they also tilted the table, ran a flashing light in front of me, put a small balloon in the ear and filled it with warm water, and all sorts of other wonderful stuff, so if it just the air they are doing....
I already got the idea it is NOT going to be fun or something I am going to like. I already figured I will walk in that place and probably have to crawl out of there and BETTER take something to throw up in on the way home. I am SO prone to motion sickness and when I get it bad, it takes me DAYS to get over it... I am hoping that is not the case but am afraid that will be what happens. Since I am expected to see the doctor right after the test, I am wondering how much he will charge me if I throw up on him or the exam room? Am I going to be expected to remember what he tells me after THAT?

The ONLY reason why I agreed to do this test is so I can know 100% what this is and get it FIXED! I am now coming to realize, there is no quick fix and there is a good possiability.... I will not be returning back to work this trip.
