MAJOR INSOMNIA!!

Kaitlyn • Expecting twins edd November
I'm 5w2d and I cannot sleep at night. Sunday night I could not fall asleep until 6:30am and last night was 2:30am. I don't nap through the day and I don't know what to do. Anyone else experienced this? It's like I can't get comfortable and my mind won't quit racing. HELP!
Would Tylenol PM be okay to take?
