I can't get no sleep

In the words of that faithless song... I can't get no sleep! I'm always struggled with periods of insomnia but this one is badly timed! I'm now worried I won't have the energy to actually give birth as I have barely slept for weeks! I'm managing two hours of broken sleep at a time. I would seriously get more sleep with a newborn! It's 5am, I'm due to be induced in 28 hours, please pray for me to fit 8 hours in somewhere!
