Great link
I found this site helpful.
Nothing really worked for me other than eating small amounts, frequently, because as soon as I got hungry... well, you know. And don't get overtired. Sucking on a lolly or an iceblock can help, especially while getting something prepared to eat. Nothing would stay down for me other than carbs, in the first half of pregnancy - so mainly potatoes, hot chips, pasta, etc. Avoid overly acidic food because it is NOT nice coming up. And when you feel like you will throw up, skull some water - it's much nicer throwing up water than stomach acid and bile.
There are some medications available from your midwife/GP/obstetrician if you get really desperate. I ended up on a cocktail of meds, which did provide a little bit of relief, but not completely.
Best of luck, big hugs!
