Suddenly started vomiting in the middle of the night?

I am a guy, I ate the same dinner everyone else did, I did not over eat, I am not sick, I do not drink nor do I take any medication. I woke up around 4am and unfortunatly started throwing up, well of course after brushing my teeth (and cleanup) I went back to bed, still feeling somewhat off key I rolled over and then within seconds I had to throw up again.

Needless to say last night was not my most comfortable night, 4 hours later and 7 or so more times (stomach was empty after the 3rd "wakeup" call). If I sit still I'm fine but my stomach now feels very uncomfortable and even somewhat slightly painful, I'm just assuming its because of constantly throwing up. Now I have never experienced anything like this nor heard of anyone thats has either, so what the heck could of caused this?

I am a 22 year old female. ive had the same problems, its been going on for the last 8 months or so. It doesn't happen to often, but I wake up in the middle of the night feeling extremely dizzy, to the point where I have to run to the bathroom and through up. It goes on for a few hours. Then after I through up my stomach hurts really bad. Like the worst cramps ive ever had in my life. Ive search everywhere and cant find a single thing that helps.

I too will wake up in the middle of the night dizzy and vomiting. I feel like I am drunk; but I'm not. My doctor put me on anxiety medication. I still wake up getting sick every once in awhile, but it is not as bad or often. But I was never told why this happens and I am still concerned and would like to seek another opinion but I have no health insurance. I have been taking this medication for 2 years now and I do not want to continue taking it but i know once I stop I will start getting sick again.
