hi there, yes i get visual disturbance all the time, its awfull! i was told by consultant its vertigo or like vertigo. iuve had it for a year, i get it almost constantly, feel so disoriontated, cant travel in a car etc, very very hard to deal with indeedy. ive just been on topiramate, i had the most awful side effects with this drug ever!!!!! they were insaine, but this was the only drug that eased my vision. but i couldnt handle to side effects. I suffer with chronic daily migriane with visual disurbace. have a read of my post, its the last one, by my lovely. ive written about the vision bit, dont know if its exactly what you get. i find it really hard to describe.
