Thanks for that chichi, the same thing happens to me - I can be doing nothing and then just out of the blue it happens. On the good news side, I managed to get my drivers licence re-newed, on my own, it wasn't easy but I left my apartment this am and stood in line for my license. I had already had 2 attacks today before I left so I figured my chances were good of not having another one (lol). Anyway, this is major for me and just wanted to share!!!
