Dealing with morning sickness at work?

I am currently 6 weeks and 1 day pregnant. I started getting all day sickness about 5 days ago. I feel sick ALL day long, have no appetite, and throw up what I do manage to eat. I've tried eating before getting out of bed, ginger ale, sipping Sprite, eating toast....I'm just not sure I can handle 6 or 7 more weeks of this. What makes it worse is that the only time I feel somewhat comfortable is when I'm lying down. I have a full time office job and have been miserable the entire day. My bosses and coworkers know about my pregnancy but I don't think they understand just how horrible I feel. I go to the doctor tomorrow and I'm going to request some anti-nausea medications, but what can I do until then? I can't even concentrate on my work because I'm just trying to keep down my lunch.
