I have very severe morning sickness. I try everything: peppermint, I ordered particular tablets with Vitamin B6, I drink ginger tea, I stopped coffee, and I eat plain food (very small portions throughout the day). Anything else you tried that helped?
I tried everything including the little anti-sickness bracelet too! In the end the only thing that helped me in reducing it - not taking it all away sadly - was the liquid vitamin B6 a few times a day! And eating first thing when getting up in the morning - plain toast helped! But I had to ride it out and the sickness eventually went away completely around week 12-13! I hope you start feeling better very soon. I know how awful it feels!
Ginger biscuits and cream crackers really helped me. Have them by your bedside so that as soon as you open your eyes you have a few bites. Then lie down for a bit before getting out of bed, if you rush it you will throw it all up again.
