What has worked for you?

This is my second pregnancy, my first one was horrible - I lost 25pounds by 12 weeks, was in hospital for fluids at least once a week - I realise the chances of me having it again is high - so after lots of reading, I've decided to start treatment before I start vomiting.. So far on my list to take is:
Unisom+B6
magnesium (tablets and an oil on the skin)
I also have a variety of antinausea meds from the Dr... What I'm looking for is anything that helped other people! (Already doing eating every few hours and drinking as much as I can, so far I just have the nausea - no vomiting)
Thanks.
