Ugh I get them, I hate them.

I get the vomiting and the blind spots when I have them. Light and sound don't typically make them worse, but movement does. Boy does it ever!

I feel your pain I really do. I get them once every 2-6 weeks and I stay in bed all day every day (as often they last 2-5 days for me) until it goes away. I don't like medication though so I'm not on meds to help them.
