I had HG with Lauren and lost ~40 pounds throughout my pregnancy so I know allllllll about remedies.

Here are common ones:
- crackers
- eat something before your feet hit the floor in the morning
- ginger (tea, candy, snaps, etc).
- vitamin B6
- vitamin B6 + Unisom
- motion sickness bands (ex. Seabands)
- eat LOTS of protein - shoot for 75 g a day
- clear carbonated beverages
- preggie pops
- chamomille (sp?) tea
- eat frequent, small meals
- eat before you get hungry
- get lots of rest
- avoid fatty foods
That's what I can think of now. I'll add more if I think of them. You can also get prescription medication to help control it. I was on Phenegren and then Zofran with Lauren. Neither helped me, but those 2 meds help the vast majority of people.
