HI, I can so sympathise! I am going thru the same thing at the moment.
I was very bad last week, had to have 2 days off work and basically sat in bed with a bucket, not nice.
I found these blackmores morning sickness tablets which contain vit b6 and ginger, I have found these extremely helpful, as this will be my second day (if I make it!!) without gagging. but, the only downfall I have found with these is that you need to eat first otherwise they just come straight back up! and they taste foul!!
bundaberg ginger beer was good, but I threw it up a bit too often and I cant even look at it now, watermelon is good too, I also stocked up on icypoles and find these really good.
I am now having just a low level constant queasy feeling, occasionally getting worse but then I know I need to eat, AGAIN!
I hope you feel better soon, I know how much it sucks.
