I feel like I'm going to throw up when I wake up?

Sometimes, I'll wake up with this intense feeling that I'm going to throw up. I'm certain I will, but if I lay still it goes away within a few minutes. This happens probably 1-2 times a month, though sometimes I'll have streaks where it will happen every day for a week. I also loose my vision (every thing gets light) and hearing momentarily, sometimes simultaneously, once or twice every week, and sometimes daily. It's only completely gone for a few seconds, but it takes a few minutes to get completely back to normal. I also feel nauseous after I eat almost anything, for years now. Often, I can only eat 1-2 meals a day and very little at one time. I usually eat dinner around 5, and go sleep at 10. There's 15 hours between dinner and breakfast the next morning, so I should be hungry, but it takes a couple hours after waking up before I can eat again. *lose my vision
