I didn't sleep all night and I really wanted to just go outside and lie on the snow and breathe in the air ? I feel like I want to sleep so badly that my eyes are red, but I can't fall asleep (did anything help anyone else fall asleep? How do you fight insomnia)? Plus, I'm still feeling pretty bloated, is this how it will be until the baby arrives?
