I know how that feels all right! I was so sick with my first baby I lost over 22 pounds. With my second it wasn't bad because I was still nursing my first. For some reason nursing really helped me with the sickness. However, with this third baby (I'm now in my fifth month) I felt terrible. I tried everything-aromatherapy, homeopathic medicines, special foods-you name it.
What worked for me: Eating and drinking whenever I felt nauseated. Resting as often as possible (lying down really helped). Big slices of watermelon. Eating homemade sprouted wheat bread. Ginger (drinks, lozenges, essential oils). Bergamot essential oil (bath with dead sea salt or in the aromatherapy lamp). Eating Wendy's mandarin orange chicken salads. Letting my husband take care of the smelly jobs-from changing the kids diapers, emptying the trash, cooking and doing the dishes (Okay. He did almost everything! ) Keeping my mind occupied and my body at rest. This time I didn't lose any weight, but I didn't gain either.
What didn't work for me: eating chocolate or tomato sauce (eww! Just stay away).
Eating dairy products (especially cheese). Garlic and white pepper. You get the idea....
I don't know of any real cure. I do know that some people take a half pill of Unisom-but I think this is quite dangerous. Others take B-6 pills. Some take a cocktail of the two. One of my friends talked me into it and, because I was desparate and sick, I tried the Unisom. Yikes! I couldn't breathe after taking it although it did take the edge off my naseau. I decided after that scary experience that no drug was worth it. The best cure for me has been time and rest. Luckily after 12 weeks I'm usually in tip top shape again.
Good luck! Morning sickness sucks rocks. I hope you don't get a full blown case.
