Sleep Trouble

Having sleeping trouble lately. Not sure why. Here I am lying in bed closing my eyes hoping to fall asleep but after 45 minutes I am still wide awake. Last night was even worse. I felt like I just closed my eyes the entire night but not sleeping. I could hear the sound of the ceiling fan the entire night. Ok, I am going to give it another try right after this. Don't want to end up with a headache at work tomorrow for not having enough sleep. Good night.
