Hmmmm, I don't have double vision, I just have crappy vision!! The heat makes me wanna sleep & I can't take hot showers for very long at all, I have passed completely out on 5 occasions. Now I've leaned to open the door & cool the water down. But that has only been in the shower. I can still do everything, other than being tired & that my eye is droopy & occasional weakness in a localized spot you wouldn't think anything is wrong with me other than I complain about it!! I guess I've had some sensory issues but that's about it..
