Morning sickness

What would you say is severe? I'm being sick atleast 3 times a day, in the morning and early afternoon. Then feeling sick most of the day :-( I had sickness with my daughter but didn't know about tablets from doctors etc so I just suffered through, but I can't do that this time because she has nursery & I work.. Everything makes me sick, I've tried plain biscuits, drinking ginger infused water. I just can't keep anything down untill about 5/6pm but I can't not eat till then every day :-( my doctors isn't open untill Tuesday ugh
