Vomit in the morning if less than 10 hours of sleep.?

Changing my diet, that's a little vague, don't you think? My diet has changed a few times over the past few years as I became more healthy and started having to eliminate some ingredients due to stomach issues, but even when I am otherwise perfectly healthy and not bothered by stomach ailments-- if I can't guarantee 8 hours of sleep, I can't go to bed or I won't be able to get to work in the morning. I will puke in the morning and feel nauseous the rest of the day.

I have had every stomach test known to man and they found nothing. I have had my stomach, intestines, esophagus, and gall bladder all checked specifically, plus a full abdominal ultrasound. Everything was immaculate and the doctor said it was just stress. It's not.

And yeah, we all need to go to the doctor sometimes for our safety, but a medical test costs several thousand dollars. If I could afford that I could afford insurance. ;)
