Patient :My sister has always smacked her mouth in her sleep--even as a child (she is 23 now). It drives me bonkers, and I would like to know what the cause is behind the effect. She doesn't snore much, but she is a restless sleeper. I don't think the cause would be anything serious because she doesn't have any other obvious markers of such things. I'm just curious to know if perhaps she may have a slight sleeping disorder that could be remedied easily to give her better sleep quality.
Symptoms: Lip smacking during sleep, restless sleep, slight snoring--but not unusually so
