Try to cool off a bit, cold seems to help keep nausea down. If you can find something light your stomach will accept, nibble on it. Hunger makes nausea worse so just try to sit back and nibble on things or suck on a mint. Good luck, I terrible nausea with my first pregnancy.
That almost sounds like your actually sick... not just the typical morning sickness.
Talk to your doctor. I had such bad morning sickness I had to be medicated all the time
I found that papaya enzyme tablets helped a lot with morning sickness in the beginning, peppermint, lemon water, eating something small every 2 hours helped also bc I had low blood sugar
