I am suffering quite badly had to take two nights off work last weekend (I only work three) and vomiting quite badly and suddenly.
But I haven't been sick since saturday morning, what I've found helps is:
-Sleep, lots and lots of sleep, tiredness really affects it (for me it's the biggest contributor to my MS, was last time too)
-Eating regularly, I have found if I go a long time between meals I get so ill.
-Ginger nuts, really help
-Bottled Vimto, full fat! God I have only just discovered this but to sip on while we are out at groups or whatever has really helped.
-Sea bands, I got mine from amazon for something stupid like £1.60
-some kind of carbohydrate before bed, a slice of toast or a crumpet, does help to settle the tummy.
-and before you wake up eat a biscuit and let it be absorbed before getting up
Hope that helps xxx
