I don't know what quack doctor you have...but uh...
"An increased level of NVP was associated with decreased risk of miscarriage (p < 0.01). Although there was no association between NVP and threatened miscarriage" NVP = Nausea and vomiting during Pregnancy.

Have you tried certain sents and foods? Ginger and Lemon are both known natural stomach settlers. You can eat Ginger snaps, ginger tea. They even make this AWESOME lemon scented lotion now at Bath and Body works.
You might also want to try nibbling on some saltines while you are up gonig pee or getting a drink of water in the middle of the night.
There are other things that can increase feeling sick like drinking WHILE you eat. No seriously I'm not joking. If you drink your drink while you are eating it can make you feel worse.
It's a vicious cycle. You feel like crap so you don't eat and then your empty stomach gets all burbly and you feel even worse so then you SERIOUSLY don't want to eat. I used to Fall apart when I got pregnant if I didn't have a steady stream of something to nibble practically. My head would hurt my stomach would hurt I'd get pallid and shakey. It's just very very good for you to TRY your damndest to get some food in.
Even if all you are eating is top ramen with a bit of soy sauce or something it'll help to quell the uprising in your stomache. Identify foods that don't automatically make you retch and sorta live on them for awhile.
I totally understand the seeing food and wanting to puke thing. Just a whiff of cooking ham and I'd be gaggin.
