Sick to the point it hurts

I'm 7 weeks and 4 days, I know morning sickness is part of the deal and I was expecting it but its getting to the point I dread getting up in the morning. As soon as I get up and start moving around I start heaving, and since it's when I first get up theres nothing to come up. For the entire first half of my day is spent running to the toilet throwing up nothing but bile to the point I'm in tears and not being able to eat anything and only drink water. I have a dr appointment next Wednesday but what can I do till then?
