If you had bad morning/all day sickness, when did it go away?

I posted a question earlier and got no answers. I am 9 weeks pregnant with my second and I can't eat. I eat maybe 2 or 3 bites of something and I feel like I have had Thanksgiving dinner. Cooking is even worse. The thought of cooking makes me feel sick and the smell of cooking makes me actually get sick. I feel like I have a stomach flu all the time. Its constant nausea. I did NOT have this with my first. Meat triggers me worst of all. I just dont know what to do. We are spending money on food out all the time just to avoid cooking but then I hardly eat anyway. Im so tired of being this way, I am miserable. My doctor has put me on a rx for zofran dissolve tabs and I take one every 8 hours. It really doesn't help how I feel very much and it certainly hasnt changed my appetite.Any tips?? How long did your morning sickness last? Thanks!!
