What do you mean when you say you can't keep anything down? If you are immediately throwing up after eating or drinking, you may have hyperemesis gravidarum and should call your doctor.
I'm taking diclectin (b6+unisom) and it really helps the nausea. I nibble original triscuits when I feel sick, with sips of water. I'm hoping to buy preggie pops today. I have zofran on hand for vomiting, but I've only needed it once (I had HG last time, so I had some left that hadn't expired).
Re: How to deal with nausea?
I also ordered the B-natal lozenges online. Hopefully something works!
