I never had sleep problems until I became pregnant. Now, I have the same problem sometimes. I have no trouble falling asleep, but if I wake up in the middle of the night, I can't fall back asleep. Right now I have an infected wisdom tooth that is impacted, so I'm in a lot of pain every night even with Tylenol 3, so I haven't slept much the last few days. I can't wait to get this stupid tooth out!

I would talk to your doctor if your sleep issues are interfering with your daily activities.
