This has been happening to me for about a year. It started when I moved out to go to college and it has been persistent since then.

Basically, in the morning, I will wake up with light nausea and as I slowly get out of bed, it turns into heavy nausea, and usually by about 7am I am puking (or at the very least, dry heaving and spitting up mucus). Once I'm finished puking, my nausea will subside for the day and I go back to normal.

This happens once or twice a day for about a week, give or take two days. I have a weeklong episode every couple months, just about. (The first was October, then December, then April, then May, then August, then November -- that brings us up to date).

I've been tested several times since then and I am not pregnant. I've asked a few doctors, and the only real help they've been is that the last one gave me some anti-nausea medicine called Zofran. Nobody has been able to tell me what's wrong, though, and I was hoping you could help elucidate this for me, or at least give me suggestions as to what it might be.
