I am sorry you are feeling so poorly.
I know I am lucky. I get at most 15 mins of mild nausea when I get up. My mum didnt have ms either so I wonder if its genetic.
I do get disconcerted at my lack of symptoms though. Damned if you do, damned if you dont!
Good luck with the ginger, I have a smootie every more with a hint of ginger and think its lovely, and I believe that it has other health benefits so I would go for it. Good luck and I hope the ms subsides.
I have also heard ginger biscuits are useful, if you can get them in the Netherlands?? XX
