Eew! Are you sure it isn't being caused by something else? (Not trying to discount that you could be having ms, just brainstorming) One night I woke up and was sick, I thought at first it was ms, but then I realized that I had horrible heartburn and I was throwing up nothing but acid. Once I ate something and took some papaya enzyme, I felt 200% better. I still get nauseous if I go too long without eating (3 hours or more...ugh), and that will continue to make me sick until I eat. I know it sounds counter-intuitive, but having something in your stomach might help.
Good luck hon!
