Nausea

Ok so things are getting pretty desperate now. My GP isn't interested, I went into boots, nothing they can provide me with.
So o have just spent £40 on recommendations from other forums and this one. Not that anything o have tried yet has worked.
The nausea is constant and taking over my daily life. I've been in bed all weekend and only get a fancying for particular food and nothing else will go past my lips without gagging and retching.
Are there any other recommendations- 
I've purchased travel bands, ginger chews and enough preggie pops to sink a small ship..... Aromatherapy oils vitamin B6 etc!!!
It ruining this joyous time for me. I have to go out for a meal in 3 days!!!! No one yet knows!!!
