sleep problems

Reva
Am I the only one who goes to sleep early and then wakes up wide awake at 2:00 then I am up for generally 2 hours until I can get back to sleep? Tonight was different though. I woke up and tried to fall back to sleep 4:00 hits and I had like a mental breakdown. I never experienced this with my first and have no idea how to handle it. Does anyone have suggestions?
