I am a pretty sound sleeper. I do wake up sometimes (I share the bed after all with one husband and two giant cats) but I can usually fall right back to sleep and having woken up momentarily never bothers me. The only time I can't sleep is if I have to pee, but I hate to get up once I am in bed. It's so dumb since if I would get up and go right away I would go back to sleep in about 2 seconds. I usually wait until I really have to go before dragging myself out of bed.
