i've had bouts of insomnia my whole life, but it seems to have gotten worse with this pregnancy. i can be dead-ass exhausted and try to go lay in bed, and lay there awake till 2 or 3 AM. Melatonin has not helped me. Unfortunately, it may just be a symptom of the pregnancy. Your body will rest when its ready. I try to stay as busy and active during the day now so I tire myself out as much as possible in order to fall asleep at a decent hour. My insomnia has seemed to get better, but now I'm constantly waking up every hour to pee, and my husbands snoring wakes me up periodically too. I haven't gotten a good nights sleep in months.
