no sleep

Kay
I am literally so tired and do not know what to do at this point .!! I am 36 weeks 5 days , I do not get any sleep and it's making me sick. I get headaches, stomachaches, and nauseous on and off all day and I'm sure it's because I lack sleep. I will go to bed at 4/5am and get back up at 9ish and stay up just to repeat the same thing again. I've tried taking unisom which is a sleep gel that I was told is safe to take. I have no getting any sleep still. At suggestions? I am so delirious at this point and crying out for any help
