It's just part of the process. I didn't sleep well (or through the night) for a couple weeks. It didn't do any harm. My body made me sleep when it needed it. I'd sleep for a couple hours here and there and then 12 hours straight.
It takes a while.
Don't use alcohol to help you sleep. It's a trap.
I drank SleepyTime tea and other calming teas. I ate well. Exercise during the day helped me sleep at night. I stayed off the news sites and listened to only Classical Instrumental music on Pandora.
Keep going.
