Aww....... I feel so bad for you, cos I've had no m/s, but on the odd occassion have felt nauseaous and that was enough for me! I had a gf who had m/s for both pg for the whole term and she ended up eating cos it made her feel better but then she put on stacks of weight
I'm sorry that I have no words of advice for you, but I do have sympathy. I really hope it passes.
