I know many women experience nausea early in pregnancy... anyone have some useful ideas on how to ease the nausea so I can function at work or what I can do to actually eat?

I've tried pretty much everything nurses have suggested from crackers before I even sit up, sipping water and small meals, to taking unisom and vitamin B6, and seabands.... I've tried different fruits, cereals, granola bars, and whatever else I can possibly think of to eat through nausea. I pretty much have to force myself to eat. I'm constipated. I'm tired. And it seems as though something will work one day and make me want to vomit the next...

And that's another thing... I feel this terrible nausea and turning of my stomach at times, but no puke. I fear puking, but I wonder if it would make me feel any better, so I've tried not to fight it but whenever I feel I'm about to, it just sits there on my chest and in my throat and won't come up.

I just want to eat, and be able to go through my day without wanting to keel over and just sleep away this aweful feeling.

Help please?
