My wedding is Saturday, and I haven't been able to fall asleep for the past 3 nights. I NEVER have trouble with insomnia. I don't think I'm that anxious, but when I lay down and get close to falling asleep, I all of a sudden remember something else I need to check on or an email I need to send. I can't wait for Saturday- not only to marry FI but also to have all this planning behind me!
