Third Trimester Insomnia

Sorry need to rant. I can't get comfy enough to sleep. I'm so tired that my day to day is hard. I thought you were supposed to try to sleep as much as possible right now because you weren't going to get any sleep once baby comes. Honestly I guess my body is just trying to get me used to no sleep before she gets here. Tips on getting to sleep are appreciated. No medication though my hubby gets paranoid if I have to take Tylenol for anything lol so I keep it to a minimum.
