I use travel bands (and I'm surprised no-one at work has called me on them yet!) and find that they're not a miracle cure but they do take the edge of the nausea. Basically if I remove them I'm sat at my desk frantically trying to stop myself from throwing up in my bin. With them on, I'm just conscious of where my bin is in case I need to throw up in it. 
I found ginger biscuits were ok, but mostly because they were stodgy food as the ginger content isn't enough to be effective. Things like rice cakes were just as good but less calorific. However, I got some crystallised ginger from H&B which is much more effective, though a bit overpowering. I actually got a pack which has chocolate coated crystallised ginger as well, which is more palatable.
Struggling in the evenings at the moment. I tend to crash out on the sofa as soon as I can after cooking food and putting DD to bed. I tried playing some PS3 last night, but the camera movement made my nausea really bad so I had to stop.
I'm experiencing pregnancy brain too, PFJ! Last time I completely lost my sense of direction, which was frustrating but not too crippling. It came back in the months following birth. This time, I've lost my memory! I keep losing track of what I have and haven't done. Bit of a problem at work and home.
