LOL! Well that 9.5 hr one was my breaking point, actually. I was in the ER with some GI complications that made it very hard to sit still while they dug. I didn't realize how much time was going by because I was so focused during each attempt. It was nuts-- hospital policy required me to have an IV in before I was admitted. They finally got one in, and it blew on the way up to the room. The admitting doc insisted I'd need another one in, but it was 2am and I actually growled at her.
