Jaimee, I'm being trying to "mesh" the vomiting with MG. This is all I could possibly figure out: When I get double vision in all directions EXCEPT forward (this is hard to explain unless you have had it) -- I see double peripherally to the right, upwards, to the left, and downwards. It makes me POWERFULLY dizzy. Like I have to hold on to something or I will fall down. Anyway, my mom and sister suffer from inner ear -- and when they get THAT kind of dizziness, they have AWFUL vomiting episodes -- almost like projectile vomiting -- it seems to go on and on. They take Mecl--something, well the other name is antivert, for this. I wonder IF you have double vision that makes YOU so very dizzy that it upsets YOUR stomach? The docs say that this is what happens with inner ear.
