I had all day sickness everyday from 5 weeks to 16 weeks.It was horrible,I vomitted anything from food to stomach juices to bile to blood.It could get as bad as 12 times of vomitting a day
Nothing worked for me,not seabands,not ginger tablets,not ginger tea,not medicine prescribed by doc.Eating plums only helps me for 10 mins,after that,it makes it worse as what comes out later will be acidic stomach juices.Could not & did not feel like eating during the daytime,the only things i could eat for lunch are non acidic fruits,and my first proper food/meal will be a very small portion of rice + vege +fish/meat at dinner.Milk for supper.
subsequently luckily from week 16 to week 28,the vomitting gradually reduced to 3 times a day ,then 3 times a week then totally gone.
I'm now in week 32 and morning sickness has seemed to crawl back into my life but it isn't as bad as last time.Vomitted twice yesterday,and only feel the nausea but no vomitting occasionally today.
One thing that I found that could provide the most relief for me previously was rubbing some medicated oil above my lips and temples.Too bad i only discovered this method when my nausea was almost ending,maybe you could try it too and see if it works for you.
It isn't easy to go through all these,I know but do still take care!
