I have been having a lip biting issue during the night and end up becoming very restless half way through the night. help?

Sounds like: you are very ANXIOUS and the anxiety is intefering with your sleep..you need to discuss this at length with your Primary Care Provider who may prescribe an anti-anxiety medication for night use or refer you to a mental health professional or both. Are you also depressed??? Have that talk...there is help available! Hope this helps a bit! Dr Z
