Acupuncture doesn't work. Clinical trials with sham needling and needling at fake points show it has zero effect.
I absolutely sympathise if you're feeling rotten . I had hyperemesis and it was just wretched - I was given meds for it and the first batch didn't really work but the third set did help a tiny tiny bit.
Please try not to get into the 'nasty chemicals' thing. Everything is chemicals :) natural isn't always better (arsenic is natural and that's not terribly good for you...)
I was unlucky and nothing cured my sickness but if I can suggest a few things?
Dehydration makes it much worse. I thought I wasn't too bad because I'd been sipping fluids but when they put me on a drip in hospital it was a case of oh my god they are putting the life force back in my veins
The less you eat the worse you feel. I couldn't face the kitchen so dh brought me tiny portions of the few things I could stomach - yoghurt , apples and chocolate were my diet for weeks! Don't worry about being healthy beyond the banned list, eat what you can when you can.
Rest as much as you can
Drugs aren't the enemy! There are well tested and safe drugs that can help and if the first line ones don't work, go back and try others.
It is awful to feel this sick, it really is. I puked every single bloody day up to delivery then it was like flipping a switch once ds was out.
It will pass, hang on in there :)
