Oh I am feeling for you.
I have just started the quesy feeling myself. I am just 6 weeks preg and have already spent some time in hospital from too much vomiting in need of a drip.

My last preg I was sick for a long time but not too bad. I found eating whatever it was that I felt like often helped. KFC chips did it for me. Ginger was also great. This time I am using sea bands. I only got them yesterday because I was really sick but today am feeling a lot better. Go to the pharmacy and ask for travel sickness bands.

I know what you mean about worrying because you feel a bit better. I do the same thing all the time.

Hope this helps. Hang in there.
