I normally have to set 3-4 alarms over an hour period and wake up slowly. My entire life I've been a groggy coffee needing person in the morning. The past few days I've been WIDE awake at 5-530. I get up, use the bathroom, try to fall back asleep but I feel too awake. One day I got back to sleep and woke up at 8 feeling like a log I was so exhausted feeling. Is waking up early a pregnancy thing??
