i had very little m/s as such but i have had ligament pain all the time
so i'd rather throw up
Unless you throw up all the time B)
I had ms from day one to the end. Some things I found helped were
small meals often (if you get hungry it's worse)
carbohydrates but not greasy ones
bottled water (no flavour).
If you find you are being sick regularly keep water around and when you feel naseus drink some. It means there is at leat something in your stomach to throw up and it dilutes what's there so the acid doesn't burn your throat as much (sorry if tmi). I always had a bottle of water in the bathroom.
Medical options are available like maxolon but only work if you can keep them down. If you are really bad they can put a drip in. If they do ask for the maxalon also to be put in via drip. Once it's in your system it's easier to keep the other ones down. It gives you a few days vomit free.
Hope your feeling better soon and it does stop eventually (says me who's still thrown up a few times post birth as the hormones start to return to normal <_< )
Edited to add: I found up &go drinks the best for breakfast.
