Answer: I'm early in my pregnancy (between 5 and 6 weeks) and can't have a full night's sleep either. First of all I have a hard time going to sleep and then when I do fall asleep I wake up early too. I've tried focusing on my breathing and taking long, slow breaths, but it doesn't always help. Maybe you can try reading a book (use a flash light if you can't turn the light on). Otherwise I don't know what to tell you, just make sure you take a cat-nap later in the day.
