I suck at getting to sleep. Always have and should think I always will. Once I actually get to sleep though, I tend to be fine. Deb's right: hormones sure don't help - always have the most trouble sleeping when I'm PMSing. Exercise helps a lot in allowing me to get to sleep more quickly. I don't know how much of it is that I'm obviously physically more tired and how much of it is that I've had some quiet thinking time whilst I'm riding/running/swimming/walking/whatever and don't end up only having the thinking space when I'm supposed to be sleeping.
