How to deal with nausea.

I'm currently sitting on the toilet at work in tears. This morning sickness is getting the best of me. I've been throwing up since I woke up this morning, had to pull over 2 times in traffic this morning so that I won't throw up all over the steering wheel. I also have diarrhea. The doctor said that it appears to be normal but I'm going to go in on Friday if it doesn't get better. I'm only 9 weeks so I have a ton of time to go but I'm miserable right. Are any of you all experiencing diarrhea also and what do you all do about constantly throwing up?
