I wasn't sick too much with my son, but when I did get sick oddly enough Dr. Pepper seemed to work for me. Though with my little girl I was sick the entire first trimester and what helped me out was a product called Preggy Pop Drops. They taste just like candy and help with morning sickness considerably. I hope you don't stay sick for too long and get to feeling more of yourself soon. Oh, try to eat small meals each day so you have something on your stomach that doesn't "weigh" you down.
I was sick with the morning sickness up until about probably 30 weeks or a little less. I can't quite recall. Nothing worked for me to cure the nausea until my doctor prescribed me Zofran/Ondansetron 4 mg. It worked wonders for me and If I didn't take it as soon as I woke up I would be sick all day long, but usually started to work within 5 minutes of taking it. I am now 33 weeks with my first child. Talk to your doctor about it if nothing else helps your nausea.
i had that same issue actually and i did the mint thing at work as well lol i also ate TONS of sour punch straws mmmm lol but yeah its because of the pregnancy if you do try the ginger candies try eating one before your small meals to prepare your stomach cant promise fabulous results but it will help or maybe have one after its up to you =)
